I've seen such happen and hunting it down required me to use the command line.
Let's see if I can find an example.
Great. Examples of locate and find.
My iTunes tracks are stored on an external hard drive in the folder:
I want to make a new iMac aware of them so I can play them using iTunes. It is running Lion (10.7.2),
I uncheck "Copy tunes to iTunes media folder..." in iTunes Preferences, select Add to Libary... and navigate to [hard drive]/iTunes
The process starts fine - lots of track names scrolling past at the speed you'd expect. But then it freezes on the track name "download.mp3" and has to be Force Quit.
I don't appear to have a track called "download.mp3". I have used Spotlight and Finder to search for it and looked manually in the likely place (it appears to be very early on in the process). I have also made hidden files visible but to no avail. The closest I have is the folder:
[hard drive]/iTunes/Album Artwork/Download
After Force Quit the local iTunes folder and content appear not to have been updated at all.
Any thoughts as to:
revealing the file download.mp3?
Thanks in advance.
