fsutil quota [enforce] <volumepath>
fsutil quota [modify] <volumepath> <threshold> <limit> <username>
fsutil quota [query] <volumepath>

Parameter Description
disable Disables quota tracking and enforcement on the specified volume.
enforce Enforces quota usage on the specified volume.
modify Modifies an existing disk quota or creates a new quota.
query Lists existing disk quotas.
track Tracks disk usage on the specified volume.
violations Searches the system and application logs and displays a message to indicate that quota violations have been detected or that a user has reached a quota threshold or quota limit.
<volumepath> Required. Specifies the drive name followed by a colon or the GUID in the format volume{GUID}.
<threshold> Sets the limit (in bytes) at which warnings are issued. This parameter is required for the fsutil quota modify command.
<limit> Sets the maximum allowed disk usage (in bytes). This parameter is required for the fsutil quota modify command.
<username> Specifies the domain or user name. This parameter is required for the fsutil quota modify command.

Remarks

  • Disk quotas are implemented on a per-volume basis, and they enable both hard and soft storage limits to be implemented on a per-user basis.

  • You can use write scripts that use fsutil quota to set the quota limits every time you add a new user or to automatically track quota limits, compile them into a report, and automatically send them to the system administrator in e-mail.
