Cleaning up Windows

[M4573R]

I'm hunting down large files on my OS partition to free up some space, and I came across a rather large file and I'm wondering if I can delete it.
The path is: C:\Users\Me\AppData\Local\Microsoft\Windows\WER\ReportQueue\Report0ab97878\WER5986.tmp.hdmp
Its over 300 megs. Is this a crucial file?

You can delete it safely, unless you do your own debugging.
It's a uncompressed version of an error dump.

I just realized that disk cleanup removes it. I thought it didn't because I just did disk cleanup. Thanks.
