After juggling my computer that had ~3GB of space left on the HDD consistently, I decided to run Window's Disk Cleanup to see what it could do.
A few things I found in there I had some questions about:
89GB of Temporary files: Should I be concerned about this? I haven't cleaned these out in the 1/2 year I've had this computer but it seems anomalous to say the least. Is there some malicious software generating such a ludicrous amount of temporary files, or is this a relatively normal amount for not having cleaned it out in a while. Furthermore, is it safe to delete temporary files even if they're not malicious?
Restore points and shadow copies: Safe to delete?
Hibernation files: Windows tells me if I delete these it'll be impossible to hibernate y/n?
and there are a lot of other error logs and windows generated files that look like they're okay to delete. What do you guys think?
