Win32_DiskQuota class
The Win32_DiskQuota association WMI class tracks disk space usage for NTFS file system volumes. A system administrator (SA) can configure Windows to prevent further disk space use, and log an event when a user exceeds a specified disk space limit. An SA can also log an event when a user exceeds a specified disk space warning level. This class is new in Windows XP.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.
