About Command X
Cut and paste files and folders in Finder using Command+X and Command+V.
Without this app, you have to first copy (Command+C) and then remember to move (Option+Command+V).
You simply set up the app once and it runs in the background.
The moving of files and folders are handled by Finder. The app just intercepts cut and paste commands when Finder is in the front and then simulates copy and move commands.
If you don't paste after cutting, nothing happens and the files stay in place.
