There is only one file type that uses the .VVV extension:
Virtual Volumes View Catalog
A VVV file contains a catalog created by VVV (Virtual Volumes View), a program used to catalog content of removable volumes, such as DVDs and CDs, and files and folders in a directory. It stores an index of files and folders scanned from a removable disc or directory. VVV files also include metadata about the folders and files, which allows them to be searched by a user.
