Invisible Gif File Taking Up Massive Space On My Hard Drive

I was testing the limits of that method I described in another thread of creating really good gifs. I inputted a really long video (over a minute), and the process crashed. Thought it might but the command prompt wasn't snapping back to its usual starting position (ya know, just the folder name>blinking cursor) so I just closed it. Didn't think that'd do any harm. Well I just checked my hard drive and I only have a few hundred megabytes where just before I had gigabytes. I tried looking for the file I'd unsuccessfully tried to create so I could delete it but it's nowhere on my system. I searched with Everything and I tried View Hidden Files but I still couldn't find it. What do I do? I need my drive space back. The computer's acting OK. Doesn't seem to be any damage. It's at a reasonable temperature and running normally but I need to get rid of this massive phantom file.

 

Do a full shutdown then restart, run a cleanup, including today's temp files. Recheck free space, report back.

 

Thanks. Will do.

 

If it helps (haven't rebooted yet) but I just organised all my files through Everything in order of size. The biggest ones that I don't know anything about are hiberfil.sys (located just on the C drive, no folder, 3 GB), magick-6216bEJnmIAqf7oV (in AppData\Local\Temp, 2 GB, presumably something to do with ImageMagick, I guess; could be connected to this as the gif creating method does involve an executable that's associated with ImageMagick), and pagefile.sys (again located just on the C dfive, 2 GB).

 

Uh-oh. Still haven't rebooted but I just opened Disk Cleanup just to learn how. Never did it before. It's telling me I can only clear a maximum of a few hundred MB. If I reboot and then allow it to scan again, it might tell me more?

 

Well I rebooted and the system came back on normally. Rebooting somehow managed to clear over half a GB on its own but when I ran Disk Cleanup again, it still told me I could only clear a few hundred MB. I selected Temporary files and clicked Clean up system files but it started running another scan for some reason. This scan's taking a lot longer than the last two. I managed to clear up about 2 and a half GB deleting that magick file from the temp folder, then deleted system restore points and that got me back another GB. So I'm back now at around 5 GB. Disk Cleanup just finished its second scan and told me I have a 2 GB folder of old versions of Windows Updates that are no longer needed. So I'm gonna get rid of that and the Temporary files again and then I'm gonna run CCleaner lastly. Hopefully nothing like this'll happen again.

 

So you're running a System drive with only 7GB of free space, that's not ideal.

 

It's a pretty shitty computer so it doesn't really matter. I'll be replacing it asap.

 

What's the total capacity of the hard disk?

 

449 gigs.

 

7 GB free from 449 GB?
I'm surprised the computer is running at all!
