Hdd labeler...

I am very new to programming and Im learning every day. What I want to know is, is there a program out there than can look at your Hdd and figure out what folder is for what games and label them. Cause I dont know about anyone else, but after trying to get most of my games to boot from the XBM screen I believe I might have doubled up dome games. You know when it says copy the USIDIR over and thats basically the whole 30 GB game. So now its in 2 places. And Lets say that the first try didnt take so I end up copying the contents over to another folder cause the first one didnt work.
Or is there a program that can look into .pkg files and see where its saying to put all the important files for the game to work?
Any ideas?
