Okay so there must be some file error going on, on an older windows 7 PC i have. Never had this problem with a PC ever, but the c drive completely filled itself up. We are talking overnight it filled up over 800 gb. I'm a bit worried and am going to run windirstat when I get home to see who the culprit is. Would appreciate it if someone could help me out as I've never had this problem and don't know exactly what to do to fix it and prevent it from happening in the future.

UPDATE: I ran Windirstat and the windows folder is the largest using 60gb, which in it's own probably shouldn't be using that much. Anyways Windirstat claims out of all my computer files my c drive is only holding 90gb of data, yet windows says its holding over 800gb. Anyone know what might be up. Oh and just to add I cleared my temp files before running windirstat and it only had like 1gig of data in it.

Hey mate, try running chkdsk for disk errors.

Try using Disk management under Computer management [Control Panel/Admin Tools] see if the results are any different to explorer

You might also check hiberfile.sys and hibernation and paging file sizes too.
