Understanding User Quota Usage in Google Workspace with GAT+ #
How to find a user’s storage quota usage in Google Workspace using GAT+
GAT+ lets you quickly see how much storage space each user in your domain is consuming.
Navigate to GAT+ > Users > Quota.
You will see each user of your domain and the Quota available.
- Quota used – overall quota used by the user
- Quota used for Drive – overall quota used by the user for Google Drive only
- Quota used for Gmail – overall quota used for Gmail only
- Quota used for Photos – overall quota used for Google Photos only (not part of Google Drive)

Conclusion #
GAT+ serves as a powerful and granular auditing tool, providing Google Workspace Administrators with complete visibility over their domain’s storage use.
You can instantly audit individual user quota across Drive, Gmail, and Photos by navigating to GAT+ > Users > Quota.
Furthermore, for a deeper look into shared resources, GAT+ is essential for accurately identifying the total size of Shared Drives a user can access by filtering the GAT+ > Drive section and enabling the Size column.
By combining these two audit areas, GAT+ equips administrators with all the necessary metadata for effective storage management, reporting, and capacity planning.
