Re: 2 million files
Well, how many files do you have on your system?
From the command prompt run chkdsk on all your disks. It will report the number of files in the summary. And possibly it will report errors.
On my c:-drive (with Windows 7) I've got 130.180 files (and 0 errors). So 2 million files is quite a lot. That's why I said it might report errors.
