The key here: any disk manipulation of files/names done outside of windows media will result in windows media "correcting your changes". It will overwrite and place files where it thinks they should be and occaisionaly will put some in the recycle bin.
If you want to change file locations/some file attributes directly on disk, you need to turn off the windows media service, delete it's database, then do your direct disk changes. THEN turn the media player service back on, start media player and
let it rebuild the database.
This is information previously given on the user help community with a few comments
1.Shutdown windows media player
2.Stop the media sharing service. Go to Start->Control Panel->All Control Panel Items->Administrative Tools->Services
Right-click on the “Windows Media Player Network Sharing Service” and select Stop.
(change view to small icons to see admin tools)
3.Navigate to “c:\Users\”your username”\AppData\Local\Microsoft\Media Player. Now delete the files named CurrentDatabase_***.wmdb
and LocalMLS_*.wmdb. (deleting the .wmdb will usually do the trick, hidden directory so usually have to type the path)
4) Do your changes on disk
5.Start the media sharing service in the control panel
6).Now start Windows Media Player and watch it build up your library again.
(might need to do this: Hit "F3" and
enter the location where you have moved your music to. If it is on muliple drives, check "All Drives". Let it finish)
Disclaimer: Rebuilding the library will NOT delete the
actual music or video files, but it WILL remove extra information like ratings, playcount and Last Played Date. These steps below will include making a backup of the library so you can always put it back in case you wish to revert to the old situation.
I usually run with "update music files on internet" off (some trade-offs with
this)
