Thanks, the path is correct.

AFAIR it is the user's folder /MediaMonkeyServer/mms.db (and mms.json)

i.e. on Windows: C:\Users\<yourusername>\MediaMonkeyServer\mms.db

I had some isues with MMS 0.2.1 under Windows 8.1 and wanted to update to 0.2.2.
Therefore I deleted all the old MMS files and extracted version 0.2.2.
When starting the new version I noticed that MMS logs mentioned successful scans of repositories that I had configured in version 0.2.1.
Where does MMS store that information?
