Wow, I thought that was a stupid question. Thanks. Somehow I missed that advanced options link.
I have the latest version of Firefly, but I only got the name of database by reading other forum posts. I’ve tried just rescanning, but that hasn’t worked. The database always gets stuck after only scanning one directory. Unfortunately, deleting the database didn’t work – it still only scans the same directory. I changed the Music Folder but it still doesn’t scan all the sub directories, but I can’t figure what’s so special about those directories.
