There are some system files you seem to not be able to access. Use an If/Else statement or what-not to avoid it. The same applies to "pagefile.sys" (error I came across not too long ago).

These files (hiberfil and pagefile) are virtual files - they doesn't exists on HDD, but are creating during system boot - this is why they can not be read

The file actually exists and if you change the system's pagefile to point to another, you can delete the old. And if it's just an  empty file and the MFT reserves the disk-space for it for the system to use, the "virtual memory" data will still exist on the HDD.

Is that supposed to mean the file doesn't exist? Then if it doesn't exist.. you can't delete it, right?.. ;)

You'll notice "..Delete the Pagefile.sys and the Hiberfil.sys files." within the second and the first one is obvious. Nothing like deleting files that don't exist.. ;) Of course Microsoft doesn't know what they're talking about.. :[

Sorry, my fault based on folowing MS words:
>>Windows NT uses a paging file for virtual memory called PAGEFILE.SYS.<< Agreed these files exists but are heavely protected by OS.

Win-98 had paging files and other sys-files and vb6 never had a prob. I miss 98.
