So I recently reset my PC, and I was looking at all of the files, and I found these 4 random files. What are they and can I delete them? Was it just caused by the bloatware that Windows 11 downloads? Thank you!

Hi Sam
If those files are on the root of your C drive, then you can safely delete those files (if you are not blocked by permissions errors)
Disk Cleanup will only delete temp files from the two Temp folders in Windows, it will not even see temp files stored anywhere else on your PC
I dont exactly know what these files are, nut they have appeared after I reset my computer I think. I do not remember them being there before. When I try to open the dump stack file it says I do not have permission even though I have full permission and am an administrator. I don't think they are temp files because when I run disk cleanup and get rid of temp files they are still there.
Hi Sam
I am Dave, I will help you with this, those files all look like temp files produced by an app crash.
Where exactly on your PC are those files you have found?
mdmp files are usually produced after an application crashes
If you open that DumpStack text file in Notepad, what text is in that file?
