Managing disk space is a constant concern for server administrators, and one way to prevent users from monopolizing storage is to implement quotas. Windows Server 2012 R2 supports two types of storage quotas. The more elaborate of the two is implemented as part of File Server Resource Manager. The second, simpler option is NTFS quotas.
NTFS quotas enable administrators to set a storage limit for users of a particular volume. Depending on how you configure the quota, users exceeding the limit can either be denied disk space or just receive a warning. The space consumed by individual users is measured by the size of the files they own or create.
NTFS quotas are relatively limited in that you can only set limits at the volume level. The feature is also limited in the actions it can take in response to a user exceeding the limit.
The quotas in File Server Resource Manager, by contrast, are much more flexible in the limits you can set and the responses of the program (which can send email notifications, execute commands, generate reports, or create log events.
To configure NTFS quotas for a volume, use the following procedure.
1. Open File Explorer. The File Explorer window appears.
2. In the Folders list, expand the Computer container, right-click a volume and, from the shortcut menu, select Properties. The Properties sheet for the volume appears.
3. Click the Quota tab to display the interface shown in Figure 2-11.

4. Select the Enable Quota Management check box to activate the rest of the controls.
5. If you want to prevent users from consuming more than their quota of disk space, select the Deny Disk Space To Users Exceeding Quota Limit check box.
6. Select the Limit Disk Space To option and specify amounts for the quota limit and the warning level.
7. Select the Log Event check boxes to control whether users exceeding the specified limits should trigger log entries.
8. Click OK to create the quota and close the Properties sheet.
9. Close File Explorer.
