In any case, if you hold down the shift key whilst clicking on the "Delete" option in most file managers, the file will actually be deleted instead of being moved to "Trash." (Some managers can be configured to offer an option to "Trash" a file and a different one to "Delete" a file. I, personally, use KDE for my desktop and krusader
as my file manager, and set my krusader
to "Delete" and "Don't ask for confirmation" since I have file recovery tools to help if I really
mess up, but I've never need to use them. So far.
