Troubleshooting Weird File taking up 400+ GB of space

[KokoKid]

Describe the problem

There is this file thats 400GB+ on my friends system.

What have you tried?

Googled it a bit.

Hey. Here's what happended.

By my quick research, the file might contain old data from the previous OS. Did you recently upgrade? Might be kind of like an Windows.old folder. This has never happened to me so unfortunately I can't help any further than saying use the built in windows clean manager to delete that file. Or delete it manually. I know if it was a Windows.old file, it could only be deleted with the windows clean manager tool (well that is the simplest method anyway).

He upgraded to win10 during the summer not in september

If he did the Upgrade he would have a Windows.old folder in his C: Directory

I know. Windows.old can become corrupted. This file IS in the C directory so it is more likely to be that than it to not be. Some people report this file being created before an upgrade. More reason for me to have said about it.

Have you google it? Because this file is not malware, even upgrading Windows 8 to 10 will not taking up that much.

 

[KokoKid]

Yeah. No solution though.

Yeah. No solution though.

Well...........tell your friend make a system restore point then delete that 400GB file. Once that file is delete, let him use his computer for at least 2 weeks to see if any problem occur.

One of the possible theory is failure to conduct those old Windows Files properly hence from the root word 'Safe to Delete'.

Use a cleaer tool to properly remove that 400 GB, assume no important files contain.

Use windows disk clean up and run a system clean up option. If anything found just delete it.

well you can transfer it to external hard drive and delete it, see what will happen. Once i had this weird file like your friend it was like 30gb, it was in download folder without extension, the only software that deleted that file was Full-Disk Fighter.
The only drawback at that time it deleted also utorrent files...(...Appdata-Roaming-utorrent)

Never saw a file like that (something similar after upgrading from 8 to 8.1 but not with those dimensions). I'd merely delete it. Windows is unlikely to use such a file as far as I'm concerned. Try using a 3rd party software and not just windows explorer (not sure it's able to do that at all).

Other users have experienced this, should be Safe to Delete.
