UpdateMedia is a daemon that constantly scans for media files in the /home/public and each /home/user_xxx folder which is created for each family member, and any media is added to the pluto_media database, File table, and attributes and cover art go into the Attribute and Picture tables. Under /home/public and /home/users_xxx is a data subfolder which contains the actual video, audio, pictures folders. The /home/user_xxx directories themselves will contain system files for each user, like email boxes, and the main login for that user. That's why there's a 'data' subfolder.
