I had been losing space on Drive C for awhile and it seemed odd to me as I rarely store things on Drive C, therefore the space should not be going down.
It ended up I had 255 GB (!) of files stacked up in the Windows Error Reporting Service queue in C:\programdata\microsoft\windows\wer\reportqueue
Definitely worth checking from time to time if you have apps that crash a lot and use Windows Vista.

IS IT SAFE TO DELETE THESE FILES???
Yes
how can you disable these logs…i dont want them!
Hello Jordan,
I have the same problem in my Windows Server 2008. The folder C:\ProgramData\Microsoft\Windows\WER\ReportQueue has its size increasing all time. I was looking for a definitive solution and didn´t find yet. I stopped the Windows Error Reporting Service and the problem still occurs. I made a change in the registry to tell WER to save its files in another partition, but it didn´t work. So much bad!
Another folder (C:\Windows\WINSXS) has an incredible size of 8 GB. And the worst is that I found that it´s not safe to delete the contents of that folder.
Do you have new comments about it?
Hello
As far as disabling them — see the link in the post above.
As far as WinSXS it seems that’s the new dll cache for windows…those files would benefit greatly from compression, so changing the folder to a compressed folder would probably help somewhat…

Found how to clear these.
Control Panel
System and Security
Action Center
(left panel) View archived message
This will list all of these reports and give you the options of clearing them one at a time, or a button to Clear All.
I’ve updated my post with a link on how to disable this feature entirely

Thanks for the help
my VPS hade 16gb of logfiles and i dident know why
how do i know what app that is doing all errors ?
In Windows Vista Business you can delete these files at Control Panel / System and Maintenance / Problem Reports and Solutions / View problem history. Highlight the boatloads of old problems you no longer care about, right-click and choose Delee.
Hi i have a similar problem
how do i find the error source ?
Thansk!
Yes, thank you VERY much. Our Windows 2008 server had this problem, and had 80GB of log files. We had a non-critical service that was failing for months without our knowing, so I wouldn’t suggest disabling. I would simply set up some sort of disk space monitoring, and add checking this path to your toolkit, as it may actually serve useful in circumstances such as this.
I was almost out of disk space and discovered that ReportQueue was taking over 3 GB.
I came here to find out if it is safe to delete it and I am under the impression that it is.
