I always recommend taking a backup of your MediaMonkey database before using my remote to do anything. Even though it has been tested thoroughly for many years now, without issues, I can never guarantee complete safety.

To take a backup of your database, navigate to %APPDATA%\MediaMonkey (you can enter that directly in Windows Explorer, or navigate to something like C:\Users\AppData\MediaMonkey). This folder contains all MediaMonkey settings. The “MM.DB” file is the database, but you can backup the entire folder too.

MediaMonkey have more details in their knowledge base.
