File explorator with custom removal and copy functions I am looking for a file explorator that have customizable move, copy and remove functions. Which strategy would you recommand? Is there any file explorer with customizable commands or should I modify the source code of an existing one (`nautilus` typically)? The custom commands should be GUI based: not interested in having a terminal in parallel to the file explorer for instance.

**Thunar** allows you to add custom actions to the right click menu.

From the menu bar, select "Edit > Custom Actions". Then you can set a name and the command for your action. In the command field `%f` will be substituted for the path of the selected file.

More instructions and examples can be found here: <

Unfortunately, I don't think it works with removable media in the sidebar. Only files.
