some time back there was discussion about songs building up and sorting them into their own folders.  someone had posted a batch file that did this very thing, but i think there was an issue with making a folder for each song, even if the group was the same.  regrettably i didn't keep the link and now cannot find reference to it.  i've done the search feature but come up empty.  anyone remember this, and better yet have a link?  thanks

Check out the latest version of Custom Game Toolkit (CGT).  Just added a new feature called CDLC organizer.  It takes your CDLC collection and sorts the CDLC into ArtistName folders and automatically renames the CDLC in ArtistName_TitleName_v# format.  This new feature can be found in the FileManager tab.

Ok i have been working on making a bat file to load seperate folders into the game & managed to work it out, so what this bat file does is load a menu before the game starts, with song catergories, then you just type a number on the keyboard corrosponding to the song catergory in the list, then press enter, this will load the game with the song catergory that you chose.

what it does in the background is move folders from the dlc folder to the rocksmith temp folder except for the song folder that you chose in the menu, therefore rocksmith only loads that folder ;-)
