Hi Guys,
I dont know if this is still a problem, but I will tell you what I did. I wanted to simply change the name of the music folder I use to store my music. I do not store all my music in itunes as my music started with a Zune player and I like having it organized my way, not iTunes way. Anyway, I wanted to make a simple rename of the folder from MP3 (started this folder 16 years ago) to Music. of course it broke all the links and couldnt find the music. So what I did was:
1) made a copy of the iTunes Music Library.xml file
2) renamed the music folder from MP3 to Music
3) opened the copy of iTunes Music Library.xml file using wordpad or the like
4) did a search and replace for the previous path with the new path (for me I just used /Music/MP3 and replaced with /Music/Music)
5) I then renamed the previous iTunes Music Library.xml file to something else and removed the "copy" out of the name of the iTunes Music Folder I just changed so it would read this new file
6) Reopened iTunes and changed the music folder location in the preferences-advanced to the new folder name. I have the "Keep Itunes media folder organized" checked, and when it asked me if I wanted Itunes to keep it organized (or some crap), I selected yes.
When I finished, it now knew where all the songs were located and when I checked the info it points to the new location. I imagine this could be used for any transfer of folder location or name by just searching and replacing with the correct location or name.
This seemed to work for me, so if it is something that you can use, then enjoy.
Regards,
Ray
