Wow, that is an amazing little app!!!
Ok, i figured out what those two files are... Page file and Hibernation!
I disabled Hibernation, as i don't use it and now the HIBERFIL.SYS was deleted and after Defraggler's job now i got 8% fragmentation, which is my 6GB Page file (i got 6GB of ram), i'm keeping my page file!!!
I absolutely love how in Defraggler i can highlight individual fragmented block and see what it is and defrag it, it's very detailed and easy to use, GREAT JOB Piriform!!! Just LOVE it!!! Thanks!!!
Aethec thank's for your help, you really helped me figuring this out!!!
