The short answer
- Your 15 GB is shared between Google Drive, Gmail and Google Photos (and WhatsApp backups on Android). A full Gmail or Photos fills your "Drive" storage too.
- Trash counts until it's emptied, in Drive, Gmail (including Spam) and Photos.
- Two hidden culprits are data saved by apps connected to Drive and "orphaned" files you own that no longer sit in any folder.
- After deleting a lot, Google says storage can take up to 48–72 hours to update.
You open Google Drive and see a few documents, but Google says your storage is full. That’s because your Google storage isn’t just Drive. Here are the eight places your space can be going, roughly in the order worth checking.
Why Drive looks empty but storage is full
A personal Google account gets 15 GB, and that one allowance covers Google Drive, Gmail and Google Photos. On Android, WhatsApp backups count too. So a mailbox full of attachments or a phone backing up every video fills “Drive” storage even if Drive itself is nearly empty.
When the 15 GB runs out, Google’s own help center lists what stops working: you can’t upload or create files in Drive, Gmail can’t send or receive email, and Google Photos stops backing up. If you stay over the limit for 2 years, Google says it may delete your content.
1. See where the space actually goes
Go to one.google.com/storage. It shows how much each service (Drive, Gmail and Photos) is using, which tells you where to start. If Drive only uses a sliver, there’s no point hunting through your documents.
2. Empty every trash
Deleted items still count until they’re permanently deleted:
- Drive: open Trash at drive.google.com and empty it. Drive also deletes trashed files for good after 30 days.
- Gmail: empty both Trash and Spam.
- Google Photos: empty the Photos trash (called Bin in some regions).
This is the most common reason storage stays full after a cleanup.
3. Clear big Gmail attachments
In Gmail, search for has:attachment larger:10M to find emails with attachments over 10 MB. Delete the ones you don’t need, then empty Gmail’s Trash. Change the number to larger:5M to dig further.
4. Check Google Photos
On most phones, every photo and video backed up to Google Photos counts toward your storage, whichever upload quality you chose. If Photos is your biggest user, delete videos you don’t need first, since they take up far more space than photos.
5. Delete hidden app data
Apps you’ve connected to Google Drive can save data there that doesn’t show up in your file list. In Drive, open Settings, then Manage apps. For each app, the Options menu shows whether it has hidden data and lets you delete it. Disconnect apps you no longer use while you’re there.
6. Find orphaned files
A file you own stays in your storage even if it’s no longer in any folder, for example because you created it in someone else’s shared folder and they deleted the folder. Google calls these files unorganized, and they don’t appear when you browse Drive.
Search Drive for is:unorganized owner:me to list them. Move what you want to keep into a folder and delete the rest.
7. Find your largest files and duplicates
Click Storage in Drive’s left menu to list your files from largest to smallest. Old videos, ZIP archives and backups tend to sit at the top.
Duplicates are the other big one. Copies made with “Make a copy”, files uploaded twice and folders synced from more than one computer all add up. Our guide to finding duplicate files in Google Drive covers the manual searches and the tools that compare Drive’s checksums, including Axclaim.
8. Give it time to update
After deleting a lot of files at once, Google says storage can take up to 48–72 hours to update. If it still looks wrong after that, check again that every trash is empty.
Things that don’t use your storage
- Files shared with you. Only files you own count, so deleting a copy someone else owns won’t free any of your space.
- Files on your computer. Google Drive for desktop uses your computer’s disk for synced files, which is separate from your Google storage.
Work and school accounts
On a Google Workspace or school account, storage is usually pooled and managed by an administrator, and the limits are different. If you’re out of space there, ask your admin before deleting anything shared.
When cleaning up isn’t enough
If you’ve checked all eight places and still need more room, you can buy more storage from Google, or move large folders to another service. Free plans are 2 GB on Dropbox, 5 GB on OneDrive and 10 GB on Box. Our guide to moving files between cloud storage services shows how.
Frequently asked questions
Why is my Google storage full when I've deleted everything?
Deleted files sit in the trash and still count until the trash is emptied. Gmail's Trash and Spam and Google Photos' trash count too. After a big cleanup, Google says the total can take up to 48–72 hours to update.
Do files shared with me use my Google storage?
No. Only files you own count toward your storage. Files you own in someone else's folder do count, which is why orphaned files can use space you can't see.
What happens if my Google storage stays full?
You can't upload to Drive, Gmail can't send or receive email (messages sent to you bounce), and Google Photos stops backing up. If you stay over your limit for 2 years, Google says it may delete your content.
How do I find orphaned files in Google Drive?
Search Drive for is:unorganized owner:me. It lists files you own that aren't in any folder, usually because the folder they were in was deleted.
Find the copies wasting your space
Duplicates are one of the easiest things to clear. Connect Google Drive on Axclaim's Premium plan to group identical files by checksum, or start free with Dropbox and Box.
