Fix Google Drive Error: Storage Quota Exceeded

Encountering the Storage Quota Exceeded error indicates that your Google Account has reached its storage limit. Google shares storage allocations across Google Drive, Gmail, and Google Photos. When you hit this cap, syncing pauses, you cannot upload new files, and you may stop receiving emails.

This guide provides steps to reclaim storage space, locate hidden data hogs, and clean local caches.

What Causes the Storage Quota Exceeded Error?

Several hidden factors contribute to storage consumption beyond your visible files:

  1. Unemptied Trash: Deleted files remain in the Trash folder for 30 days and continue to count against your storage quota.
  2. Hidden App Data: Third-party apps and mobile backups linked to Google Drive store data silently in hidden directories.
  3. Orphaned Files: Files whose parent folders were deleted by another owner, leaving them “homeless” but still taking up space in your account.
  4. Google Photos & Gmail Backups: High-resolution image backups and large email attachments (greater than 10MB) sharing the same pool.

Detailed Steps to Resolve Storage Quota Exceeded

Follow these steps to free up storage space and resume synchronization.

Step 1: Locate and Delete Large Files

Google provides a dedicated link to list all files in your drive ordered from largest to smallest.

  1. Go to the Google Drive Quota Page.
  2. Review the list of large files.
  3. Select unnecessary files and click the Trash icon (Delete).

Step 2: Delete Hidden App Data

Many backup tools and mobile apps do not display their files in your standard Google Drive folders.

  1. Open Google Drive in your browser.
  2. Click Settings (Gear Icon) → Settings.
  3. Select Manage Apps on the left menu.
  4. Scroll through the apps. If an app has hidden data, click Options → Delete hidden app data.

Step 3: Find and Clean Orphaned Files

Orphaned files occur when you upload a file into a shared folder owned by someone else, and they subsequently delete that folder. The file remains in your account but is no longer visible in any folder tree.

  1. In the Google Drive search bar, paste the following search query and press Enter: 
    is:unorganized owner:me
  2. Inspect the results, select the orphaned files, and move them to the trash or delete them permanently.

Step 4: Empty the Trash and Force a Client Sync

After deleting files online, you must empty the trash permanently to free up the quota, and reset the local client to index the new space.

On Windows:

  1. Open the Google Drive Web Trash and click Empty Trash in the top right.
  2. Open Command Prompt (Admin) and execute:
:: Force kill Google Drive client to prevent sync errors
taskkill /F /IM GoogleDriveFS.exe

:: Clean out the local cache files to force space recalculation
cd /d "%USERPROFILE%\AppData\Local\Google\DriveFS"
del /F /S /Q Cache\*

:: Restart the client
start "" "C:\Program Files\Google\Drive File Stream\bin\GoogleDriveFS.exe"

On macOS:

  1. Empty the online trash.
  2. Open Terminal and run:
# Terminate the sync client daemon
killall "Google Drive"

# Clean out local cached database and temporary chunks
rm -rf ~/Library/Application\ Support/Google/DriveFS/Cache/*

# Relaunch the application
open -a "Google Drive"

Summary Checklist

  • Check exact usage distribution on the Google One Storage Dashboard.
  • Sort and delete large files using the Google Drive Quota link.
  • Clear hidden application data via settings.
  • Find and delete orphaned files using is:unorganized owner:me.
  • Empty the Trash folder online and run the local cache clearing commands.
