File names changed

I've used Norton Back-Up to my memory stick, as part of the 360 programme, and it's made a series of folders filled with files with complete gibberish for titles.

 

How on earth am I supposed to know which files they are?

 

 

the main folder is named '{9412A9FC-AA87-4E86-8C70-0C21882D54E1}' and all the sub folders are named '{0',  '{1' through to number 9, in which case it becomes '{A' etc through to F.

 

Once within those folders, i'm faced with the following:

i have absolutely no idea what these files are?
