I pay Google every month for 2TB of storage. Two. Terabytes. That’s a ridiculous amount of space, and yet one morning Google cheerfully informed me I was almost out of it.
So I did what any reasonable person would do. I opened Google Drive, clicked Storage, and sorted by the biggest files. And the math didn’t work. The files Google showed me didn’t come anywhere close to the number it said I was using. Somewhere in my account, hundreds of gigabytes were hiding, and Google wasn’t in a hurry to tell me where.
Here’s how I found them, step by step. If your Google Drive storage is full and the numbers don’t add up, one of these is probably your problem too.
Step 1: Check what’s actually using your Google storage
First lesson: your 2TB isn’t a Drive plan. It’s one big bucket shared by Google Drive, Gmail, and Google Photos, and each of them helps itself.
Go to one.google.com/storage and look at the breakdown. For a lot of people this is where the mystery ends, because it turns out 600GB of it is Gmail attachments from 2014. Not me. Almost 1TB of mine was sitting in Drive, and the large files Drive showed me didn’t come close to adding up to that.
If your big number is Gmail, search your inbox for has:attachment larger:10M and start deleting. If it’s Photos, open Photos, go to Settings → Manage storage and let Google shame you with your own blurry screenshots. If it’s Drive, like mine, keep reading.
Step 2: Find orphaned files hiding in Google Drive
Here’s a fun Google Drive feature nobody asked for: files can be yours, count against your storage, and not show up anywhere in your Drive. Google calls them “unorganized.” I call them freeloaders.
In the Drive search bar, type:
is:unorganized owner:me
My results were full of podcast episodes. Hundreds of them. Here’s how that happened. My co-host kept our episodes in a folder in his Drive. At some point he transferred ownership of the files to me, which moved them onto my storage bill. But they stayed in his folder. Later I downloaded everything and removed the folders from my Drive, thinking I was cleaning up.
What I actually removed was my access to his folders. The files I owned stayed right where they were, with no folder I could see and every gigabyte still billed to me.
The cleanup:
- Make sure your local copies are complete. Compare the file count and total size. Once you empty the Trash, the Drive copies are gone for good.
- Warn anyone who still uses those files. You own them, so deleting them deletes them for everyone.
- Run the search, scroll to the bottom so every result loads, press Cmd+A (Ctrl+A on Windows), and click Move to trash.
- Empty the Trash. Nothing is freed until you do.
Step 3: Other hidden files taking up Google Drive space
Orphans weren’t the only thing Drive’s large-files list “forgot” to mention. Check these too:
| Where it hides | How to find it |
|---|---|
| Trash | Trashed files still count for up to 30 days. Open Trash and click Empty trash. |
| Computer backups | If Drive for desktop ever backed up your Mac or PC, those files live under Computers in the sidebar, not in My Drive. |
| Your files in other people’s folders | Anything you uploaded to someone else’s shared folder counts against your storage. Search owner:me to see it all. |
| Version history | Every time a big synced file gets overwritten, the old versions can stick around. Right-click a file and choose Manage versions. |
| Hidden app data | Apps can store data in your Drive that you’ll never see. Check Settings → Manage apps. |
None of these show up in the large-files list, and all of them count. Sure, Google.
Step 4: Delete old UpdraftPlus backups (yes, even if you set retention)
The other big offender was a folder of WordPress backups from UpdraftPlus. This one stung, because I always set the retention limit. Keep 3 backups, delete the rest. Done. Responsible adult stuff.
Except retention only deletes backups the plugin still remembers. Move a site to a new host, restore it from a backup, or rebuild it, and UpdraftPlus can lose its record of every backup it already sent to Drive. Those backups aren’t tracked anymore, so they’re never pruned. They just sit there, forever, collecting rent from my 2TB.
Other ways backups pile up:
- Sites you’ve shut down. A retired site never runs again, so its old backups are never cleaned up.
- Staging copies. Clone a site for testing and the clone keeps backing up to the same Drive folder.
- Failed backups. Old backups only get pruned after a backup finishes successfully. Failures leave partial files behind.
- Locked backups. Anything marked “only allow this backup to be deleted manually” is skipped.
To figure out which one got you, sort the backup folder by name. UpdraftPlus names files like backup_2025-03-14-0200_SiteName_abc123-db.gz. Site names you don’t recognize are dead or staging sites. A long run of old backups that suddenly stops usually marks a migration.
The fix: delete everything but the last few backups per site, then empty the Trash. On each live site, go to UpdraftPlus → Existing backups → Rescan remote storage so the plugin knows about what’s in Drive again and retention can do its job.
Google Drive storage FAQ
Why is my Google Drive full when I don’t have many files?
The storage list only shows files you can see. Orphaned files, trashed files, computer backups, version history and hidden app data all count against your quota without showing up there.
Do deleted files still count toward Google storage?
Yes, until they leave the Trash. Google empties the Trash after 30 days, or you can empty it yourself right away.
What does is:unorganized owner:me mean in Google Drive?
It finds files you own that aren’t in any folder you can see. They usually got that way when someone else deleted or unshared the folder they were in.
How long does Google take to update my storage after deleting files?
Usually minutes, but it can take 24 to 48 hours for the total to catch up.
Checklist: how to free up Google Drive storage
If you’re paying for storage you apparently can’t use, run through this list:
- Check the Drive / Gmail / Photos breakdown at one.google.com/storage
- Search Drive for
is:unorganized owner:meand deal with the orphans - Empty the Trash (in Drive and Gmail)
- Look under Computers for old desktop backups
- Check Manage apps for hidden app data
- Prune old website backups and rescan remote storage in UpdraftPlus
One last thing: Google can take 24 to 48 hours to update your storage total after you delete things. So if you do all of this and the number doesn’t budge, don’t panic. Go outside. Come back tomorrow.
Google would be happy to sell me 5TB. I’d rather it just told me where my 2TB went.
