+      Ftop is to files what top is to processes. The progress of all open files
+      and file systems can be monitored. If run as a regular user, the set of
+      open files will be limited to those in that user's processes (which is
+      generally all that is of interest to the user).
+      As with top, the items are displayed in order from most to least active.
