Why Is My Google Storage Full? (And How to Actually Fix It)

You get the warning — "Google Account storage is nearly full" — and you open Drive expecting to find gigabytes of files. But it looks almost empty. So why is your storage full?

The answer is almost always the same: storage is shared across three services, and it's usually not Drive that's the problem.

The three things eating your Google storage

Google gives every account 15 GB free, shared across Gmail, Google Drive, and Google Photos. Not 15 GB each — one pool, three services drawing from it.

1. Gmail attachments. Every email with a PDF, photo, or ZIP file counts against your quota. A decade of newsletters, invoices, and forwarded photos can quietly consume gigabytes without you realising. To check: search has:attachment larger:5M in Gmail to find the biggest offenders.

2. Google Photos. Since May 2021, Google ended unlimited "high quality" photo backups. Every photo and video from your phone now counts toward the shared 15 GB. If you have Google Photos backing up your phone automatically, this is almost certainly contributing — often accounting for the majority of used storage.

3. Google Drive. Files you've uploaded (PDFs, ZIPs, videos, downloads) count in full. Google Docs, Sheets, and Slides are the exception — native Google files don't count toward the quota. But anything you uploaded does.

How to see exactly what's full

The quickest way: go to one.google.com/storage (or drive.google.com → Storage in the left sidebar). Google shows you a breakdown of how much each service is using. This tells you immediately whether to focus on Gmail, Photos, or Drive.

Quick fixes by culprit

If Gmail is the problem:

• Search has:attachment larger:10M and delete emails with large attachments
• Go to Gmail → Bin → Empty Bin (deleted emails still count until you do this)
• Unsubscribe from newsletters you don't read — each one counts

If Google Photos is the problem:

• Go to Photos → Settings → Storage saver — this re-compresses existing photos slightly and stops future uploads counting as much
• Delete duplicate photos and old videos you don't need
• Check photos.google.com/settings for your backup quality setting

If Drive is the problem:

• Go to drive.google.com → Storage, sort by size, and delete what you don't need
• Empty Drive Trash — deleted Drive files still count until the bin is emptied
• Move large archives to Mega.nz or Drime (both free, 20 GB each) using GTransfer

The permanent fix if you don't want to delete anything

If your files are things you want to keep but rarely access — old projects, photo exports, backups — the permanent fix is to move them out of Google rather than delete them. GTransfer moves Drive files directly to Mega.nz or Drime (40 GB free combined) for a one-time £19. Your files stay safe, your Google quota clears, and you don't pay Google monthly.
