jeremy I SAID that's how the files may have been REPLACED. Say All tracks in folder got changed to Track1.mp3 and when you say " yes to all " to warning for replacement.. it overwrites
That's what my bro did to thousands of mp3s.. And i cant sit and guess which files were deleted. :\
Now that would be only a future suggestion for mediamonkey to lock folders/files from being altered and also log such tasks.
