fman
Press Ctrl+P to quickly jump to a directory. fman remembers which folders you visit most often and suggests them first. This is so much quicker than manually navigating through directory hierarchies. Tailor fman to your needs via its powerful plugin system. Install plugins created by others, or write your own and share them with the community. fman is an alternative to file managers such as Explorer on Windows or Finder on macOS. You use it to browse directories, copy or move files, mount external drives, etc. It lets you perform these tasks much more efficiently than other file managers. This makes it extremely easy to copy or move files. You just open the directory you want to copy from on one side and the destination on the other. A simple keyboard shortcut then performs the copy. Unlike other file managers, you don't have to deal with multiple windows, drag files, or copy/paste in separate steps. File-related tasks can be carried out much more quickly that way.

4Pane
4Pane is a multi-pane, detailed-list file manager for Linux. It is designed to be fully featured without the bloat and aims for speed rather than visual effects. In addition to standard file manager things, it offers multiple undo and redo of most operations (including deletions), archive management including 'virtual browsing' inside archives, multiple renaming/duplication of files, a terminal emulator, and user-defined tools. As you can see from the Screenshots its display is split into a left directory tree-view, and a right detailed-list view which by default shows both files and directories. There are normally two of these twin panes displayed (thus the name) but this, and almost everything else, can be configured to suit your needs. It has been built and tested on all the main Linux distros, using both current and older versions. Though it has a gtk-style appearance, it's not tied to any particular desktop.
