Running out of Space (and Time): Deleting Microsoft Error Log files

(I originally saw this issue on Windows XP Professional, Service Pack 3 computers, but it appears that the same files exist on Windows Vista/7 installations)

At my place of employment, we have user's personal drives routed to our network servers, so the individual computers almost never run out of space on their respect C: drives. As so often happens in computer land, though, there are exceptions to the rule.

Usually, to free up space, you can take steps such as deleting old user profiles, clearing out temporary files and deleting old System Restore points. This time, however, I had done all of these, and the user's C: drive was still 40GB over the normal used space level! I was able to narrow the culprit down to the C:\Windows folder (a scary place to delete files, for sure), and then eventually the folder residing at:

C:\WINDOWS\PCHEALTH\ERRORREP\UserDumps

Within that folder there were thousands of ".hdmp" files, at 23.4MB each. These specific error reports were related to a printer malfunction on that computer from a few years ago. Just because you click "Don't Send" on those Microsoft Error Reports screens doesn't mean the files disappear forever!

You can safely delete the files in this folder to reclaim the space. However, keep in mind that if the computer is already having other issues, you'll want to keep the most recent files in order to analyze the error reports.
