The Win32_DiskQuota association class tracks disk space usage for NTFS volumes. System administrators can configure Windows to prevent further disk space use and log an event when a user exceeds a specified disk space limit. They can also log an event when a user exceeds a specified disk space warning level. Note that disk quotas cannot be set for the Administrator accounts themselves.
