Why are MP4 files disappearing from iTunes?
I am running OSX 10.7.5 with the latest software that will run on my 2007 Mac Pro. I have my iTunes Library on a separate internal drive and have had it that way since I got this Mac. I transfer movies to this library location via Finder and then go to iTunes and use the "Add to Library" menu option. A few weeks ago I found that when I tried to Add To Library, the movie file (MP4) would literally disappear out of the folder location on the hard drive. I have run Disk Utility and restarted the system and I still have the same issue. Any thoughts?
