Generally, in order to transmit a file on a user device to a server using a web browser, a target file to be transmitted is selected by using a browse button (HTML input tag) provided by each web browser in order to select a file or a folder There are two ways of selecting folders and using Drag & Drop.

The drag & drop is divided into a drop source indicating a source of the selected source and a drop target indicating a location of the drop source. Here, a drag source is generally a window explorer including a desktop in a window environment, and a drop target is an object (file or folder) selected from a drag source. It means a specific area of a specific application to be dropped.

Generally, when a user wants to select a target file to transmit (upload) a file or a folder to a server through a web browser, he or she uses a drag and drop function. And most web browsers also provide that functionality.

When a user selects a target file or folder to be uploaded using the drag-and-drop function provided by each web browser, there is a problem in that direct access to the file of the corresponding path is impossible due to the sandbox mechanism of each browser .

Furthermore, the problem that direct access is impossible is not only in that it can not provide scalability when a target file is transmitted to a server, but also causes a problem that a file can not be checked (opened) in advance before transmission. Here, extensibility refers to an existing IE Web browser ActiveX or a Plug-In browser of each browser in addition to the POST or PUT web standard transmission method using JavaScript, which is a script language provided by each browser. ), And the like.

The existing ActiveX or plug-in transmission method of each browser has the merit of being able to provide fast transmission and various UI (User Interface) since programmable elements can be added rather than the web standard transmission method

However, the web browser extension provided by each web browser has to be installed for each web browser like the ActiveX of Internet Explorer (Microsoft), and in recent trends, the developer of each web browser has to install the browser extension There is a tendency to provide minimal functionality.
