The game on first launch told me I have a high rate of file defragmentation, so I started the Steam degraf, and the counter started at 1,678,454%!!! holy cow bat man!
I skipped that defrag - I figured it was some kind of error with the decrypted files. It's very unlikely that it would be fragmented if you just downloaded it a few days ago. After decrypting, I manual went to the defrag option for the game and it said it wasn't needed.
