As you can see my Steam folder is full of large files that just refuse to defragment, and my file fragmentation has reached a whopping 62%!!! I just converted my hard drive to NTFS from FAT32 if that makes any difference...I dont know if the problem persisted before. Any help on how I can defragment these files would be greatly appreciated...plus you get 250 points if i like you...^_^
