Over the past month or so I have slowly watched space on my C: drive magically go away. I first realized this when I went to delete some files I had imported from an external hard drive that were useless without their installation disk (I had to factory reset my computer recently.) When I went to delete those files I lost hard drive space. Now, every time I turn on my computer, I lose between 1-9 GB of disk space.
I have downloaded WinDirStat to see exactly where it could have gone- and to my supprise, around 250gb of my hard drive no longer exists, according to the program. My Computer is informing me that 460 or so gb out of 918 has been used, but WinDirStat is informing me that 460gb out of 651gb has been used. I ran the scan yesterday, however, and WinDirStat said I had 918gb in total on my C: drive, but showed an anomaly of about 10% of space that was totally unaccounted for.
I've got no idea what the cause of this could be. I've scanned my computer for viruses and malware, and I'm currently running two firewalls. Any help would be greatly appreciated.
EDIT: I've checked the "Show Unknown" option on the WinDirStat scan, and am now being informed that 266gb of my hard disk is being taken up by... well... I don't know. I've got no clue what this could be.
RESOLUTION EDIT: I've found the problem, my PCs System Restore settings had it able to take up to 50% of my Hard Drive space. I've lowered to a more reasonable amount and have gotten the space back.
