Boot the PC into safe mode and see if the files are still being created. What is the name/extension of the files being created? Can you take a screenshot of a few of the files?

You could also open Resource Monitor and watch the disk activity to see which process is creating the files.

 

I'll boot into safe mode in a bit. How do I even find where the files are? All I know is that Disk Cleanup found them, but there's no context menu or button that lets me view them to see where they are.

You can run SpaceSniffer to see where the lost space is.
You can use Process Explorer to see what programs are using the most CPU.
Download Junkware Removal Tool, Run it, A DOS window appears, press Any key, it will scan automatically.
Download ADWCleaner, Run it, Install it, Scan, leave everything checked, Clean. Both of the last two programs will show a Text document when they are done to show you what they removed. This should stop new temp files from being created.
You can also download Temp File Cleaner from Old Timer, that should remove the rest of the Temp files for you.

I'm not sure I can even free up enough space for long enough to get anything like that installed. Every time I clear up space, including the over 20GB I cleared up uninstalling Sims 2, the temp files grow to fill the space.

Well, checking folder by folder I was able to track it down. It's the file "desktop.ini" in C:\Users\[myname]\AppData\Local\Temp

I tried opening it in Notepad++ but I get the error "Load config.xml failed! Do you want to recover config.xml?" with "yes" and "no" buttons. Then it doesn't let me close Notepad++ either. "Unknown exception" error box when I try. No matter how I try to close Notepad++. The close menu item, the close box in the corner, even using the task manager, it does that before finally ending the task.

Is there any harm in deleting that file and letting windows rebuild it?

Also, since it's that file I plugged back into the internet. Just before all this windows explorer crashed last night. It would seem to me that it apparently had some kind of issue in that file that has made it do this. Does that sound right?

 

Temp File cleaner is only 440 KB not even a MB. That should remove the temp files for you.

 

I have 0 bytes free. And it's one file. If need be, I can delete it myself without anything getting installed.

Okay, I tried to delete desktop.ini. It said it couldn't because the file was open in nvStInst.exe, which is my graphics card driver install program. I ended that process. I got an error saying that it terminated in an unusual way, but I got the process stopped and was able to delete the file. So apparently the graphics card driver update had some error, causing the file to explode in size and fill the drives empty space. As long as the process was still in use it continued to fill the space. Now that I figured it all out, I can update my antivirus again and I'm down to 738GB of free space. I'm going to be writing an email to nvidia about this because that was seriously messed up. At least now we all know what it was and how to fix it. Thanks for trying to help me, everyone.

 

Re: [SOLVED] My drive is filling itself up. I have no idea how to stop it.

Hi, you have u Torrent installed this is your problem. I am surprised your post was answered at all, we do not support p2p programs.. don't blame Nvidia blame yourself, if you continue to run this then you can be assured of more problems.
