I currently have my Steam/Rocksmith/cdlc/Song Manager on an external hard drive. If I decide I want to move this to a new computer, how do I make sure all the songs and song info is transferred over? because I'm noticing Saved File: songsInfo.xml is on my computer hard drive right now under c drive. Every time I close the song manager, it saves a few files. What does backing up user profiles do? How often do I have to back it up? The prfldb file is in my external hard drive/userdata folder
