Tunes Sweeper identified over 30K duplicates in iTunes. I carefully reviewed to make sure the selections were legit; I was impressed. It took about 15 hours to actually delete the files, but I didn’t mind, since doing it manually would have taken me at least 15 days! However, the deletinion also wiped the mapping, so that about 75% of them “cannot be found”. I’ve tried selecting the drive in iTunes’ preferences, etc. No luck. What’s frustrating is that I cannot select through Tunes Sweeper the drive holding my music and video files. I currently have a request into the Wide Angle Software for assistance. No luck. If I receive help, I’ll be sure to post an update. (If you have your library on an external HD, beware.)
