Are you the one like me who suddenly sees the Hard Disk space slowly running out more importantly going unaccounted? Do you have one or more applications that are recently crashing quite regularly then that could be the culprit. This could happen on a Windows 2003 Server or a Windows XP PC.

This happens when Windows Error Reporting is enabled on your Windows 2003 or Windows XP system. Windows Error Reporting dumps the memory into two dump files everytime an application crashes. One is a HDMP file which is an uncompressed version of the memory dump while the other is a MDMP file which is a compressed version of the memory dump file which will be sent to microsoft if you choose to.

However, if you everytime choose not to send to microsoft or if you already chose to send the files and successfully submitted the files to Microsoft then they do not have to sit there and hog the hard disk space unnecessarily and you can safely delete the files from your Hard Disk. These sometimes, especially if yours is a busy system with quite high physical memory can grow and fill dramatically in quick time.

While you safely delete it,it is important to identify and fix the application otherwise the whole memory dumping will continue to fill the hard disk space on your Disk.

To check if the files exist at the first place, simply check the folder

C:\WINDOWS\pchealth\ERRORREP\UserDumps

This is where the files reside should they be created.

For example, a set of files might look like this

w3wp.exe{time}.mdmp

w3wp.exe{time}.hdmp

These indicate a problem with the service w3wp.exe on your Windows system

Alternatively, you can disable the Windows Error Reporting feature or customize it accordingly like disabling Error Reporting for a specific application.

To do so,

1. Right-Click “My Computer” and click Properties.

2. Click Advanced and select “Error Reporting”

Windows Error Reporting Feature

3. Select “Enable” or “Disable” error reporting option accordingly.
