Adjust path for iTunes / Music files after files move

Solution 1:

The last time I moved my music library, I did the following:

Before starting iTunes, hold down "alt" (or "option") and then run iTunes. This brings up a dialogue where you can tell iTunes where the library now is.

Solution 2:

All your files should have question marks on the left like this now:

1. Double click one of them and it would prompt "The song could not be used because the original file could not be found. Would you like to locate it?" Click "Locate".

2. Find the file in the new location, and iTunes/Music App should start playing and prompt something like "Would you like to search all missing files?". Click "Yes".

3. The music App/iTunes would search and try to re-link all your music files if the file directory tree remains the same. For example, if the files used to be in D:\Music\Lay\NAMANANA and D:\Music\Lay\SHEEP, the new directories should not be E:\Music\Lay\NAMANANA and E:\Music\Lay\2017\SHEEP, the structrue should not be changed.
