When a recording medium such as a CD-ROM is set in itself, the recording medium access device 57 is set according to the control of the CPU 51 that performs processing of the window system 1. Access the recording medium.

The hard disk 54 stores an executable file including a program for constructing an application such as a window system 1 and a data management application 2 to be described later, a non-executable file including data other than the program, and the like. Also, the recording medium access device 57
An executable file, a non-executable file, and the like are also stored in a recording medium that can be accessed.

The executable file and the non-executable file are stored in the storage area of the hard disk 54 and the storage medium access device 5.
7, a storage area of the recording medium is stored in a tree structure with the root directory being the highest node. In the storage area of the hard disk 54 and the storage area of the recording medium accessed by the recording medium access device 57, information (that is, a folder) for identifying each node included in the tree structure is also stored. The folder is generated according to the processing performed by the window system 1.

The storage area of the hard disk 54,
In the storage area of the recording medium accessed by the recording medium access device 57, link information (that is, a shortcut) indicating a logical position where the execution file is stored is stored.
Is also stored. The shortcut is generated according to the processing performed by the window system 1 and used by the window system 1 as described below.

The data management system logically comprises a window system 1 and a data management application 2, as shown in FIG.

The window system 1 is an operating system (OS) that supports multi-window and multi-task application execution, such as Microsoft Windows 98 (trademark).

The window system 1 has a kernel,
The kernel executes processes to be described later and other system functions that affect the entire data management system upon receiving a call to a system function representing each function.

The window system 1 has an API (application interface) 11. API11
Consists of a group of system functions for calling a function of the application or a system function executed by the kernel.
Each system function includes information indicating an address associated with a function to be executed when the system function is called, and when the system function is called, execution of a function associated with the address is performed by an application or the like. Tell the kernel. Further, when each system function is supplied with a parameter conforming to a predetermined format when it is called, it passes the parameter to a function to be instructed to execute.

The system function group includes functions representing functions for processing the data management application 2, functions for accessing files and folders, functions representing functions of a file management system and a system tray described later, and functions for displaying a pull-down menu. , Functions to modify the registry, etc.

The registry is a file for storing information used by the window system 1. Among the registries, there is a registry related to extensions, and the registry related to extensions stores information indicating an association between the extension and an application. Then, the window system 1 uses the API to access a file whose name includes the extension associated with the specific application.
11, the specific application is executed.

The parameters supplied to the function for accessing files and folders include a file name and the like. When a parameter is supplied to this function, the kernel of the window system 1 sends the data management application 2 to a filter (to be described later) registered in the window system 1 as a virtual driver (that is, a process executed in preference to the application). Pass parameters.

The filter to which the parameter has been passed accesses the file and folder indicated by the passed parameter. When data is obtained from a file or folder as a result of the access, the data obtained by itself is supplied via a kernel to an application or the like that has supplied parameters to a function for accessing the file or folder.

The file management system includes a program (or a program for displaying a list of files (executable files and non-executable files) and folder names stored in the hard disk 54 and the recording medium set in the recording medium access device 57, or Function of the window system 1). When the window system 1 is made of Microsoft Windows (trademark), the file management system is made of, for example, Explorer.

When called from the API 11, the file management system specifies each file and each folder included in the root directory of the storage area of the recording medium set in the hard disk 54 or the recording medium access device 57. Then, a window is displayed on the display 52, and icons representing the specified files and folders are displayed on the window.

Then, the user operates the mouse 56 to
When the mouse pointer is placed on an icon on the window displayed by the file management system to specify the icon, and then the right button of the mouse 56 is pressed, the file management system performs the operation such as pressing the right button. Open the pull-down menu in response.

In the pull-down menu opened by the processing of the file management system, a character string representing an item set according to an arbitrary application processing and a character string representing an item designated by the window system 1 are displayed. Items set according to the processing of an arbitrary application include items indicating an instruction to delete a file or folder represented by a designated icon or to change the name of the file or folder. The items specified by the window system 1 include, for example, the following items that the data management application 2 requests from the window system 1 and adds to the pull-down menu. Note that the pull-down menu can display a separate pull-down menu (that is, a sub-menu) by clicking an item to be displayed by the user.

When the user operates the mouse 56 and clicks on these items, the file management system executes the function indicated by the clicked item. Also,
If the function indicated by the clicked item is an application function, the API 11 associated with the function is called. When API1 is called, its API11
Causes an application to execute the function associated with itself (that is, the function associated with the address indicated by the information included in self).

The system tray is the window system 1
Is a function of the window system 1 for displaying a list of information representing applications executed under the control of the window system 1. When the system tray is called from the API 11, an icon representing a function that can be called by an application executed by the kernel of the window system 1 is displayed.
The information is displayed at a predetermined position on the display screen of the display 52.

When the user operates the mouse 56 to place the mouse pointer on an icon displayed on the system tray and designates the icon, and then presses the right button of the mouse 56, for example, the system tray Open a pull-down menu in response to pressing a button.

Items specified by the application represented by the specified icon are displayed in the pull-down menu opened by the processing of the system tray. Then, when the user operates the mouse 56 and clicks on these items, an application for calling the function represented by the clicked item is displayed in A corresponding to the function.
Call PI11. The called API 11 causes the application to execute the function associated with the API 11 to execute the function.

The data management application 2 includes an installer 21, a setting program 22, a filter setting program 23, a folder management program 24R, an activation management program 24Y, an installation management program 24B, an extension management program 24P, and an unnecessary. It has a file removal program 24G and a registration item display program 25.

The setting program 22, the filter setting program 23, the folder management program 24R, the activation management program 24Y, the installation management program 24B,
The extension management program 24P, the unnecessary file removal program 24G, and the registration item display program 25 execute processing described below under the control of the window system 1. Note that the filter setting program 23 registers a filter in the window system 1 according to a process described later,
The filter performs the above-described processing and the processing described below.

The data management application 2 is provided by the supplier of the data management application 2 in advance by C
It is recorded on a recording medium such as a D-ROM. When this recording medium is set in the recording medium access device 57 while the window system 1 is running,
The CPU 51 controls the data management application 2 recorded on this recording medium under the control of the window system 1.
Is started.

CPU that has started processing of installer 21
Reference numeral 51 transfers the folder management program 24R, the startup management program 24Y, the installation management program 24B, the extension management program 24P, and the unnecessary file removal program 24G recorded on the recording medium to the hard disk 54.

Then, the installer 21 displays a window on the display 52, and displays
A message prompting the user to register a password and a text box for writing the password are displayed. When the user writes the password in this text box using the keyboard 55, the installer 21
The written password is encrypted by a predetermined method and stored in the hard disk 54, and the process ends.

With the above processing, installation of the data management application 2 and storage of the password in the hard disk 54 (registration of the password) are performed. The registered password is used in the processing of the data management application 2 as described later.

(Operation) Next, the operation of the data management system having the configuration shown in FIG. 1 will be described with reference to FIGS.

(Initial Processing) When the data management system shown in FIG. 1 is started, the CPU 51 responds to operation inputs of the keyboard 55 and the mouse 56 via the interface 63, and transmits the program of the window system 1 via the interface 62. Read from the hard disk 54 and start. When execution of the window system 1 starts, C
The PU 51 performs display on the display 52 via the interface 61 and sets the memory 53.

As described above, the window system 1
Are a CPU 51, a display 52, a memory 53, a hard disk 54, a keyboard 55, a mouse 56, a recording medium access device 57, and an interface (I / F) 61.
To 64 and other hardware.

The CPU 51 executes the processing of the filter setting program 23 under the control of the window system 1 to register the filter as a virtual driver in the window system 1. As a result, the filter acquires information indicating the name of the file or folder from the application that called the function that accesses the file or folder or another function of the window system 1.

(Access Mode Setting) When the user
6 or the keyboard 55 to start the data management application 2, the window system 1
Reads the setting program 22 of the data management application 2 from the hard disk 54 and starts up.

When the setting program 22 is started, the setting program 22 requests the window system 1 to
Open a window for writing the password. When the password input by the user using the keyboard 55 is written on this window, the written password is obtained.

The setting program 22 decrypts the password encrypted by the installer 21 and written in the hard disk 54, and determines whether any of the decrypted passwords substantially matches the password obtained by itself. Determine. If it is determined that they do not match, the setting program 22 displays a message not to perform the subsequent processing, and ends the processing.

On the other hand, if it is determined that they match, the setting program 22 invokes a function called by itself so that the pull-down menu shown in FIG. 3 is opened when the icon of the data management application 2 included in the system tray is designated. Requests that the window system 1 be newly registered.

Items newly displayed in the pull-down menu as a result of the registration are the folder management program 2
4R, the activation management program 24Y, the installation management program 24B, the extension management program 24P, and the unnecessary file removal program 24G, and include character strings indicating these programs.

When the user uses the mouse 56 to click on any of the items newly displayed in the pull-down menu on the system tray, the setting program 22 calls a function represented by the clicked item. That is, the setting program 22 performs the processing of the process indicated by the clicked character string among the folder management program 24R, the startup management program 24Y, the installation management program 24B, the extension management program 24P, and the unnecessary file removal program 24G. Calls the API 11 associated with.

Prior to the processing described below, the setting program 22 sets the file management system of the window system 1 so as to add a new item to a pull-down menu opened on a window displayed by the file management system. . As the new items added to the pull-down menu as a result of the setting, specifically, for example, the following items (1) to (3) are included.

That is, for example, a submenu for instructing a change in the attribute of a folder is added to (1) a pull-down menu opened when a folder is designated, and (2) an open file is designated when an executable file is designated. A character string for determining whether or not the executable file can be executed is added to the pull-down menu displayed. (3) A pull-down menu that is opened when a file other than the executable file is specified is instructed to change the extension. Character string is added.

The submenu for instructing the change of the attribute of the folder includes a “read-only” character string for the user to instruct the prohibition of writing to the folder and an instruction to prohibit the display of the icon indicating the folder. And a character string of “hide” to be performed.

As a character string for determining whether or not execution is possible, if the execution file represented by the designated icon is not prohibited from being executed, "execute prohibited" for prohibiting execution by the user. In the case where the execution is prohibited, a character string of “execution permission setting” for allowing the user to execute is included.

The character string for instructing change of the extension includes a character string of "change association" for instructing the start of processing of the extension management program 24P.

Next, the setting program 22 activates the file management system in response to a user's instruction or the like, opens a pull-down menu on a window displayed by the file management system, and enters the above-described submenu corresponding to the item (1). It waits for the included character string or the character string corresponding to the items (2) and (3) to be clicked.

When the character string "change association" is clicked, the setting program 22 detects that the character string "change association" is clicked, and executes the processing of the extension management program 24P described later. call.

When the clicked character string is a character string other than the character string "change association", the setting program 22 detects that the character string is clicked, and clicks the character string. The status of the folder or file specified at that time is determined to the status indicated by the character string, and information representing the determination result is generated.

More specifically, if the clicked character string is a “read-only” character string, the setting program 22 writes the folder specified at the time the “read-only” character string is clicked. Is generated to indicate that is prohibited.

If the clicked character string is a character string of “Hide”, it is determined that the display of the icon representing the folder designated at the time when the character string of “Hide” is clicked is prohibited. Generate the information shown.

When a character string of "execute prohibition" or "execution permission setting" is clicked, the execution file designated when these character strings are clicked is prohibited or permitted to execute. Generate information indicating that the

When the information indicating the status determination result is generated, the setting program 22 determines that the generated information matches the password written by the user after the setting program 22 itself is started among the passwords encrypted by the installer 21. The stored data is stored in the hard disk 54 in association with the data.

When the setting program 22 newly stores information indicating the status determination result in the hard disk 54, old information including contents inconsistent with the contents of the newly stored information is already stored in the hard disk 54. Then, the old information is deleted or the newly stored information is overwritten with the old information. Specifically, for example,
When newly storing information for prohibiting or permitting the execution of a specific executable file, if the hard disk 54 has old information for permitting or prohibiting the execution of the executable file, the old information is deleted or newly stored. Overwrite the stored information with the old information.

(Access Monitoring by Filter) On the other hand, when the filter registered by the processing of the filter setting program 23 receives a parameter indicating the name of a file or folder from the kernel which has called the function for accessing the file or folder. Then, it is determined whether or not the user has specified the access to the file or folder represented by the parameter.

More specifically, the filter includes data indicating that the folder represented by the delivered parameter is write-protected, and the password encrypted by the installer 21 after the setting program 22 itself is started after the activation of the setting program 22 itself. Then, it is determined whether or not the password determined to match with the password written in the above is associated with each other. Further, the filter includes data indicating that the file represented by the passed parameter is a target of execution prohibition, and a password written by the user after the setting program 22 itself is started out of the password encrypted by the installer 21. It is determined whether or not the ones determined to match correspond to each other.

If it is determined that the user has not specified the access to the file or folder, the filter accesses the file or folder indicated by the supplied parameter.

On the other hand, if it is determined that the user has specified the access to the file or folder, the filter determines that the parameters passed to the filter in a manner in which the user is prohibited from performing the operation on the file or folder are prohibited. It is determined whether or not access is instructed. Specifically, for example, when the filter determines that the folder represented by the parameter acquired from the application or the like is a write-protected target, the filter determines whether or not the parameter instructs writing to the folder. Determine.

When the filter determines that the access is not instructed in a mode prohibited by the user, the filter accesses the file or folder indicated by the parameter passed to the filter in the mode indicated by the parameter.

On the other hand, if the filter determines that the access is instructed in a manner prohibited by the user, the filter does not access the file or folder indicated by the parameter passed to the filter. If it is determined that the filter instructs access in a mode prohibited by the user, a window that displays a message indicating that access is rejected may be opened.

(Monitoring of Registry Changes by Filter)
Further, when the filter receives the above-mentioned parameters (FIG. 4A, step S11), the parameters become
It is determined whether or not it represents a registry for the extension (step S12).

If it is determined that it is to be represented, the filter stores the acquired parameters in the memory 53 (step S13), and supplies a message to the effect that registration of the registry has been instructed to the registration item display program 25 (step S13). S14). If not, the filter
It enters a state of waiting for a new parameter to be supplied.

On the other hand, the registration item display program 25 determines whether or not a message indicating that a registry modification has been instructed has been supplied from the filter (FIG. 4B, step S21). When determined, the determination in step S21 is repeated. On the other hand, if it is determined that the filter has been supplied, the registration item display program 25 acquires the parameter stored in the memory 53 by the filter (step S2).
2) Identify the registry to be modified.

Then, the registration item display program 25
For example, the window shown in FIG. 5 is displayed on the display 52 (step S23). The window displayed by the registration item display program 25 includes, for example, (a) an extension registered in the window system 1 and (b) an application currently associated with the extension (“original content”). ) And (c) an application (shown as “new content”) that is to be newly associated with the extension and that is indicated by the parameter acquired in step S22. Is displayed.

Further, the registration item display program 25 associates each extension listed in step S23 with the extension and the application to be newly associated with the extension as shown in FIG. 5, for example. Is displayed with a check button indicating whether or not the user permits the association with. For example, the shape of each check button alternates between two types each time the button is clicked, and one of the shapes indicates permission of association and the other indicates prohibition.

Further, as shown in FIG. 5, the registration item display program 25 displays, on the window displayed in step S23, an OK button for notifying the end of the work for determining permission or prohibition of association. .

For example, when designating to permit association of a specific extension with an application that is to be newly associated with the extension,
For example, the user clicks a check button attached to an extension to be specified, and the shape of the check button indicates permission for association. Further, in a case where designation is made so as to prohibit association between a specific extension and an application that is to be newly associated with the extension, for example, the user may add the extension to the designation target extension. The shape of the check button indicates that the association is prohibited.

Then, when the user determines permission or prohibition of the association and clicks the OK button, the registration item display program 25 accesses the specified registry. As a result of the user deciding whether to permit or prohibit the association between each extension and the application to be newly associated with the extension (that is, the check button of each check button on the window displayed in step S23). The contents of the registry are changed according to the information indicating the shape and the extension to which the check button is attached).

As a result, the registry changed by the application or the like is changed according to the contents determined by the user.

The processing performed by the filter and registration item display program 25 is not limited to the above-described processing. For example, the registration item display program 25 may supply a signal for inquiring whether or not the filter has passed the above-described parameter to the filter at regular intervals.

In this case, in response to this signal, the filter determines whether or not the parameter has been delivered. For example, the filter displays information indicating the determination result in the registration item display program 2.
Return to 5. The registration item display program 25 determines whether or not the filter has passed the parameter based on the returned information and the like. When the filter determines that the parameter has been passed, the filter stores the parameter stored in the memory 53 into the memory 53. Read from.

(Folder Management Program) When called from the setting program 22, the folder management program 24R requests the window system 1 to display the window shown in FIG.
In the window displayed by the processing of the folder management program 24R, icons representing folders in the root directory are displayed as shown.

Note that the folder management program 24R
If the folder in which the icon is displayed is prohibited from being written or the icon is prohibited from being displayed, the icon is displayed in a state where a color for identifying the prohibited contents is colored.

The folder management program 24 R
If the folder on which the icon is displayed includes a lower folder, the icon is marked with the lower folder as shown in FIG. Then, when the user double-clicks the marked icon using the mouse 56, the folder management program 24R further displays icons representing lower folders included in the folder represented by the clicked icon.

When icons indicating lower folders are further displayed, the folder management program 24R also colors the newly displayed icons to identify the prohibited contents imposed on the folders indicated by the icons. Displayed with

The folder management program 24 R
As shown in FIG. 6, a check button for determining write-protection, a check button for determining display-prohibition, a write-protection and display A check button for canceling the prohibition and an OK button for notifying the end of the determination are displayed.

For example, when prohibiting writing to a specific folder, the user clicks a check button for determining write prohibition, and when prohibiting display of a specific folder, display prohibition is determined. The user clicks the check button for Then, the folder management program 24R creates information indicating that the folder represented by the clicked icon is prohibited from being written and information indicating that the display is prohibited, and stores these information in the memory 53. Remember.

When the user clicks the OK button, the folder management program 24R writes the information stored in the memory 53 into the password encrypted by the installer 21 after the setting program 22 is started. Is transferred to the hard disk 54 in association with the one determined to match. When the transfer to the hard disk 54 is completed, the folder management program 24R deletes the transferred information from the memory 53.

The folder management program 24R
An update button for updating the icon display is displayed on the window displaying the folder icon according to its own processing.

When the user clicks the update button, the folder management program 24R executes, for each folder whose icon is currently displayed by its own processing,

Then, when the user clicks the delete button, the installation management program 24B deletes the invalid uninstaller stored in the hard disk 54 from the hard disk 54.

(Extension Management Program) When called from the setting program 22, the extension management program 24P requests the window system 1 to
2 displays, for example, a window shown in FIG. As shown in the figure, in the window displayed by the extension management program 24P, a list of all extensions registered in the window system 1 is displayed. In addition, in the window, information describing each extension displayed in a list (for example, description of the file type of a file having the extension) and information indicating an application associated with each extension ( For example, the name of the execution file of the application) is displayed in association with each extension.

As shown in FIG. 9, the extension management program 24P specifies on the window displaying the name of the application according to its own processing, a file for deleting the file having the extension selected by the user. Displays the extension deletion button. When instructing deletion of a file having a specific extension, the user clicks, for example, a character string representing the extension of the file to be deleted. Subsequently, when the user clicks the designated extension deletion button, the extension management program 24P deletes the file having the extension represented by the character string with the check mark from the hard disk 54.

Further, as shown in FIG. 9, the extension management program 24P displays an add button for registering a new extension, and when the add button is clicked, the extension management program 24P For example, an additional window is displayed, and a text box and an application list are displayed on the additional window.

The text box displays a character string supplied to the CPU 51 by the user using the keyboard 55 as a character string forming a new extension. The application list displays a list of executable files and the names of the shortcuts of the executable files included in the desktop folder and the start menu folder, which are folders created in advance by the window system 1.

When newly registering an extension,
While the character string is displayed in the text box, the user clicks one of the names of the executable file and the shortcut displayed in the application list.

At this time, the extension management program 24P
Detects that the name is clicked, and determines that the file whose extension includes the character string written in the text box is associated with the executable file or the shortcut corresponding to the clicked name. Then, a function for changing the registry related to the extension is called, and as the data indicating the change, the character string written in the text box and the data indicating the name of the executable file or the shortcut are delivered to the function.

As a result, the window system 1 uses the API 11 to access a file whose extension includes the character string determined by the processing of the extension management program 24P.
When an instruction is issued through the application, the application indicated by the executable file or the shortcut corresponding to the name determined by the process is executed. That is, in the window system 1, a file in which the determined character string is included in the extension is associated with the application indicated by the determined name.

(Unnecessary File Removal Program) The unnecessary file removal program 24G performs a process of deleting a file meeting a condition specified by the user according to a process specified by the user.

When the unnecessary file removing program 24G is called from the setting program 22, the unnecessary file removing program 24G
For example, a window shown in FIG. Then, as shown in the drawing, among the files stored in the hard disk 54 on the window,
A list of file names is displayed for those that match the conditions (deletion conditions) specified by the user as conditions for determining unnecessary files. The deletion condition is determined as described later using, for example, an option window displayed by the unnecessary file removal program 24G according to a user's instruction.

Displays an option button for displaying an option window on the above-mentioned window displaying a list of file names of files matching the deletion condition. When the user clicks the option button, the click is detected, and FIG. Open the option window shown in (b).

The unnecessary file removal program 24G displays a check button on the option window for determining the specific contents of the deletion process, and the user clicks the check button to change the shape of the check button. Then, it is determined that the deletion process associated with the shape is to be performed.

Specifically, for example, the shape of the check button displayed by the unnecessary file removing program 24G alternates between the two shapes each time the button is clicked. One of the shapes represents a process of actually erasing a file to be deleted from the hard disk 54, and the other represents a file to be deleted that is a folder for recycling created in advance by the process of the window system 1. Represents the process of moving to. In this case, the unnecessary file removal program 24G actually deletes the file to be deleted as a deletion process in accordance with the distinction between the two types of shapes of the check button when the option window is closed. It is determined whether to perform the process of moving to the recycling folder.

Further, the unnecessary file removing program 24G
Displays a text box on the option window for designating a feature (for example, a feature having a file name or extension) of a file to be deleted as a deletion condition. Then, the unnecessary file removing program 24G stores the deletion condition represented by the character string entered in the text box when the option window is closed, and thereafter determines the file to be deleted according to the deletion condition.

A feature of the extension specified as the deletion condition is that, for example, when the application creates a file for temporary storage in the process of processing, the file name given to the file for temporary storage by the application is a predetermined name. In the case of having an extension including the character string, the specified character string may be designated.

Also, the unnecessary file removing program 24G
Is the window system 1 on the option window.
Displays a temporary file (a file for temporary storage generated by the window system 1 in the course of processing) stored in a predetermined folder and a check button for selecting whether or not to delete an invalid shortcut. Then, when the user clicks the check button to change the shape of the check button, it is determined whether a temporary file or an invalid shortcut is to be deleted according to the shape.

As described above, according to this data management system, whether or not to access arbitrary files and folders stored therein and the manner of access can be set for each user. Further, according to this data management system, when the execution file describing the application indicated by the shortcut is not stored in the hard disk 54, the shortcut can be erased collectively. Further, according to this data management system, non-executable files used for processing an application and other unnecessary files can be removed without a user individually designating them. Further, according to this data management system, when a change in association between an extension and an application is requested by an application or the like, the association is changed according to the content determined by the user.
