“You have run out of storage” in Gmail but Drive empty

Seeing the alert “You have run out of storage” or “Storage full — you may not be able to send or receive emails” inside Gmail when your Google Drive contains almost no files is a frequent point of confusion. This happens because Google accounts use a shared storage model. Your storage quota is divided among three separate services: Gmail, Google Drive, and Google Photos. An empty Drive simply means your storage is being consumed elsewhere—most often by long-forgotten Gmail attachments, high-resolution phone backups in Google Photos, or hidden application data.

Quick Answer

Visit one.google.com/storage to see exactly which service is using your space. If your Drive is empty, the quota is almost always consumed by Google Photos video backups or large email attachments. Search Gmail for has:attachment larger:10M to delete heavy emails, and empty both your Gmail Bin and Spam folders to clear the alert.

Step 1: Check Your Unified Storage Breakdown

Do not spend time deleting small documents in Google Drive until you confirm where your storage is actually being used.

1. Open your browser and go to one.google.com/storage.
2. Sign in with the exact email address experiencing the Gmail error.
3. Review the Storage details bar, which breaks down usage across three distinct categories:
   • Google Drive
   • Gmail
   • Google Photos

Common Discrepancy Scenario:
Total Storage: 15 GB Used of 15 GB (Quota Exceeded)
├── Google Drive:   0.1 GB  (Appears completely empty)
├── Google Photos:  9.4 GB  (Consuming bulk of space via mobile backups)
└── Gmail:          5.5 GB  (Exceeding balance with heavy attachments)

Once you identify the service consuming your space, follow the appropriate fix below.

Step 2: Clear Storage Consumed by Gmail

If the storage bar shows that Gmail is using your quota, old messages with heavy attachments are usually responsible. Standard text emails take up minimal space, but presentation slide decks, PDFs, videos, and image attachments accumulate over time.

1. Search for Large Attachments

In the Gmail search bar at the top of the screen, paste the following search operator and press Enter:

has:attachment larger:10M

This filters your entire inbox, displaying only messages that contain attachments larger than 10 megabytes. Review the results, select the messages you no longer need, and click the Delete (trash can) icon. If you send or receive heavy files frequently, see Troubleshooting “Message too large” (Inbound/Outbound).

2. Clear the Spam and Bin Folders

Deleting emails only moves them to the Bin. They will continue to consume your storage space until the Bin is cleared.

1. In the left-hand Gmail menu, click More to expand the folder list.
2. Click Spam > click Delete all spam messages now.
3. Click Bin (or Trash) > click Empty Bin now.
4. Gmail will update your available storage within a few minutes.

Step 3: Clear Storage Consumed by Google Photos

If the storage meter shows that Google Photos is consuming your space, your smartphone is likely backing up photos and videos to your account without you realizing it.

1. Open a browser and navigate to photos.google.com.
2. Click the Explore tab on the left, then scroll down and click Videos. Videos consume exponentially more storage than standard still images.
3. Delete unwanted, high-capacity videos.
4. Go to Trash in the left sidebar of Google Photos and click Empty trash.
5. Adjust Future Backups: On your mobile phone, open the Google Photos app, tap your profile icon > Photos settings > Backup > Backup quality. Switch from Original quality to Storage saver. This compresses future uploads, significantly reducing how much storage they use.

Step 4: Check for Hidden WhatsApp and App Backups in Drive

If your storage breakdown shows that Google Drive is using space even though your “My Drive” folder is empty, the space is likely occupied by hidden app backups.

1. Go to drive.google.com.
2. Click the Settings gear in the top right > select Settings.
3. In the left panel, select Manage Apps.
4. Scroll down to find services like WhatsApp Messenger or mobile device backup managers.
5. If an app shows several gigabytes of stored data, click the Options dropdown next to it and select Delete hidden app data.
6. For troubleshooting Android and WhatsApp storage hooks specifically, refer to Troubleshooting WhatsApp Backup storage in Google Drive.

Step 5: Check for Orphaned Files

If your Drive storage remains elevated despite having no visible files or app data, files you previously uploaded into shared folders may have lost their parent directories. These orphaned files remain linked to your account and continue consuming quota.

To track down and delete these hidden assets, use the diagnostics outlined in How to Use is:unorganized to find hidden files and How to Find “Ghost Files” taking up space in Drive.
