Here's a problem that I haven't been able to resolve for the last two months. I've researched this problem on this forum and nothing been able to solve it yet. My work computer's c-drive keeps filling up to capacity. I have a 235 GB hard drive with very few programs loaded onto it and almost no picture or video files taking up space. The computer is hooked up to a network here where I work, but nobody else has this problem. Even if I'm able to free up several GB's of space, the c-drive will fill up in just a couple of days. I think I might have a virus. These are the measures I've tried to correct this issue: Ran Disk Cleanup which freed up about 2 GB's initially. After a couple of days, the c-drive filled back up again. Subsequently, running Disk Cleanup only free's up a few MB's now. Ran MalewareBytes, Eset online scanner, and Super-AntiSpyware programs to try to identify a virus, but neither of them can find anything other than cookies. I've also run these programs in Safe Mode. My Microsoft Security Essentials program had been removed, and I can't get it to re-install. I even tried several work-arounds listed on this forum to install it, but I still get error messages when installing. Tried the "Fix It" function Tried System Restore but apparently that's been disabled too since there are no restore points to be found Disabled the Hibernate function to free up several GB's, but the computer quickly filled-up within a couple of days. Disabled the Backup function. Deleted temp files from my user profile I also run into problems trying to install the security updates from the Windows Update function. I haven't been able to get the security updates to install for a couple of months now. Anything thing I do that free's up space will only work temporarily. The c-drive will continue to fill up in a matter of minutes or hours even if I'm away from my computer during that time. The strangest part is that if I right-click on the c-drive in My Computer, it will show that the 232 GB hard-drive is nearly or completely full (0 bytes). If I open the c-drive, select all the files and folders in it and right-click, it only shows about 51 GB's of storage space used. This does affect my computer greatly when trying to save or print even small files that only take up a few KB's. Is there any other fix that I haven't tried yet? I ran the WinDirStat utility but that doesn't show me anything other than the 51 GB's taking up storage space. Also, my hard-drive is not partitioned.

Try turning on Show Hidden Files and see if large files/directories are revealed.

I checked the Folder Option settings and the Show hidden files, folders, and drives option is already turned on.

These are the measures I've tried to correct this issue: Your first step should have been to find out exactly what is eating up your disk space. Only then can you try and fix the problem. This tool should help you. I installed that tool and it doesn't show me anything different than the WinDirStat tool; about 51 GB's of space used.

You need to determine what files are being added to fill the partition. You need to learn how to use Treesize to diagnose the problem. To investigate disk space usage run Treesize (freeware) as Administrator . Open Treesize, select Scan from the Menu and you will see a list of drives. Click on C and it will generate a list of Folders. Post the names and the sizes of the 6 largest folders and the total at the top of the list.
