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.
