I want to know if it's possible to copy and paste files from a playlist.

The reason I ask that is because when I highlight a bunch of files in the playlist and drag them to another place, the original files get deleted.

I would also like to know if it is possible to just copy and past items in a playlist.

I found out that if you click and drag the songs you want from the play list to another folder or drive and hold down ctrl before you drop them, amarok copies them to that folder, so just hold the ctrl button when you're dragging and dropping.
