Description

Specifies the amount of disk space that must remain free for use. If the amount of free space falls below the value of this entry and below the percentage specified by the value of the DiskSpaceThreshold entry, then the Server service records the following event in the System Log in Event Viewer:

"The <disk-letter> disk is at or near capacity. You might need to delete some files." (Srv Event ID 2013)

If the value of this entry is 0, then the system does not check whether free disk space has decreased below a specific number of megabytes. However, unlike DiskSpaceThreshold (which when equal to zero prevents both checks of free space), the value of this entry has no effect on the check specified by DiskSpaceThreshold.

This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
