Shared Folder Quota Not Accurate

In this case users were complaining that cannot share files in shared folder on Windows Server 2008 R2 file server with quota assigned on that shared folder. The shared folder had hard quota assigned, and according to FSRM (File Server Resource Manager) Quota Management 90% was used. Here is the screenshot showing that only 10MB were available for that folder:

Dir command was running with elevated credentials, and I was gaining same output from dir command when running under SYSTEM account. So, I was suspecting that quota calculation for that folder was not accurate. In order to trigger quota recalculation I was using Dirquota, with following syntax:
dirquota quota scan /path:<Path to folder>
After running this command, FSRM Quota Management was showing that 9X% were free (instead used) and users started to share files without getting notified that are reaching maximum quota limit for that folder.


  1. This issue is fixed in hotfix KB2679054:
