EmelFM2

emelFM2 is a GTK+2 file manager with a simple and efficient interface, divided into three "panes" (two display the directory filelists and the third displays the output of commands executed within the program). A built-in command-line, toolbar buttons or assigned keys (entirely configurable by user) can be used to initiate commands. A flexible filetyping mechanism provides user-determined actions for desired filetypes.
