Sorting out my HardDisk

I have nearly cleared/sorted out my HardDisk, .
I have upload some games to and not listed as i dont think not worth a word but just to clear my hd. 
i come to point where i need to resort any unneeded files/images/gamese/tc from my hd so i can maintain/backup easy incase of another Data corruption..
BTW this image is edited using lunePaint and ZuneFig
