XFM is a powerful file and applications manager program written using the X
toolkit. It contains virtually all of the features that you would expect in a
file manager -- move around your directory tree in multiple windows, and move,
copy or delete files with simple mouse operations. Directory displays are
updated automatically in regular intervals when the contents of a displayed
directory changes. The integrated application manager allows you to load files
into your favourite applications from the file manager by dragging icons. It
can also be used as a "shelf" onto which you can place files and directories
that you are currently working with. A special LOAD action for application
files enables you to manage different application groups.
