HKLM\SOFTWARE\Policies\Microsoft\Windows NT\DiskQuota

Data type Range Default value
REG_DWORD (Not in registry) | 1-6 (Not in registry)


Specifies the units used in the default disk quota limit for new users of an NTFS volume.

This entry is used in configuring the disk quota management feature of NTFS file system volumes. Along with the value of Limit, which specifies the number of unit in the disk quota limit, this entry restricts the disk space that new users of an NTFS volume can consume.

This entry stores the value you enter in the Default quota limit Units box of the Default quota limit and warning level Group Policy. Group Policy adds LimitUnits to the registry when you enable the Default quota limit and warning level policy. If you disable the policy or set it to Not configured, Group Policy deletes this entry from the registry. Then, the system uses the amount of physical space on the volume as the disk quota limit.

Value Meaning
(Entry does not appear.) The disk space available to users is not limited. The disk quota management feature uses the physical space on each volume as its quota limit.
1 KB (kilobytes)
2 MB (megabytes)
3 GB (gigabytes)
4 TB (terabytes)
5 PB (picabytes)
6 EB (exabytes)

The quota limit established by the policy overrides the user settings for quota limits. Also, when you set a quota limit, the system disables the corresponding options in the Select the default quota limit for new users of this volume section on the Quota tab so administrators cannot change the limits while a policy is in effect.

This entry applies to all new users as soon as they write to the volume. It does not affect disk quota limits for current users or affect customized limits and warning levels set for particular users (on the Quota tab in Volume Properties).

Change method

To change the value of this entry, use Group Policy. This entry corresponds to the Default quota limit and warning level policy (Computer Configuration\Administrative Templates\System\Disk Quotas).

Note Image Note

This entry is effective only when disk quota management is enabled on the volume (see Enable . Also, if disk quotas are not enforced (see Enforce), users can exceed the quota limit you set. When users reach the quota limit, their status in the Quota Entries window changes, but users can continue to write to the volume.

Tip Image Tip

When you select a limit, remember that the same limit applies to all users on all volumes, regardless of actual volume size. Be sure to set the limit so that it is reasonable for the range of volumes in the group.
