New iTunes Media Folder location won't "stick"
This question pertains to iTunes running on Windows 10. I had my iTunes media folder (not the library itself, just the media folder) stored on a mapped network drive (D:\Music\iTunes). I needed to move the media files to a new drive (call it U:\Music\iTunes), so I did the following:
1) Updated the media folder location under Edit | Preferences | Advanced from D:\Music\iTunes to U:\Music\iTunes.
2) Went to File | Library | Organize Library and selected Consolidate Files. That resulted in iTunes copying all of the media files to the new location (U:\Music\iTunes), as expected. With a library of about 130GB of media files this took some time.
After doing this, when I right click any song in my library and choose Show in Windows Explorer, it does show the file in a path under the new location, also as expected.
However, here's the question: when I close and reopen iTunes, the iTunes Media Folder location under Edit | Preferences | Advanced keeps reverting back to the old location (D:\Music\iTunes) even if I change it again to point to the new location (U:\Music\iTunes).
I tried disconnecting the network drive (D:) and then opening iTunes. When I did this, the Media Folder location was displayed as the location of my library file on my local C: drive (iTunes Library.itl).
Since asking iTunes to show me where my songs are located in Windows Explorer shows that they are in the correct (new) location, I suspect that if I never add another song to the library I'd be fine as is. However, if I do add new media, I suspect it's going to try to put it either in the old location (D:\Music\iTunes) - at least until that network drive goes away; and then once that's gone, it's going to want to put new media files into the Music\iTunes folder on my local C: drive - which will quickly run me out of space since my C: drive is not that large.
Is there a way to force iTunes to accept the new location of the Media folder once and for all?
