Be carefull with that solution!
There is a button named "Delete" that fails to delete the files we were talking about here.
And there is a button "Remove from list" or whatever it is called that is right above the "Delete" button. This button only makes it so that the file is not listed in this list (d'oh). It does NOT delete it from the file system and the file is still there, occupying your space and can still be recovered (in case you have some sensitive data there).
That was just a warning. It's up to you what you want to do there.
