Everything has been working fine. All of my files are on an attached usb external drive. SongSergeant builds the list of duplicate files properly. I had selected "remove from Itunes and move files to trash." The playlist and last play boxes are unchecked bottom left. I select merge marked. It starts deleting the files and songs from Itunes. I watch the files being deleted in the finder. However the files are not going to trash. I also tried running trash-it utility to reinitialize my trash in case I had something wrong. Still not fixed.
Any suggestions? I'm running Lion 10.7.5. My Mac can't run Mountain Lion because of its age. It's from 2006.
Thanks for your help. Paul
