Thanks for the link, but it is for moving the source location of my music eg from the C drive to the D drive. However, my music has never been moved. It's always on the d:/ drive. It's just for some strange reason MusicBee has got confused and thinks that it's on the c:/ drive.
The instructions that Mayibongwe linked are for exactly this problem. Relink Music File Paths doesn't move the files, it changes where MusicBee looks for the files. So if it thinks they're on C:\, then relinking from C:\ to D:\ will tell it to look for the files on D:\ instead.
Unfortunately that doesn't work if the location for the original files didn't exist in first place (such as when you change to a new computer and decided to change how you organize your folders/files), or after deleting such location after moving the files. This is because it doesn't give you an option to simply ignore the "from" location files in the given folder and just check the "to" location.
I've never had
any program that's looking for lost files ask me to locate the the old, now non-existing location, and it's just completely dumb for such a function to require it, not to mention mandates a entirely counterintuitive file transfer process for the user if they have to restore or recreate the old location. It should just simply ask for which folders to check like any other import function.
I had to instead learn about and use the Locate Missing Files tool and then manually input the folder just to get it update the file paths after an
hour of struggling to look for a solution (via google) to a fairly basic import function given unnecessary requirements and complexity.
