Google Drive Storage Full? Here's What to Do (Without Paying Monthly)

You try to upload a file and Google Drive refuses. Or Gmail stops accepting new emails. The reason is almost always the same: your shared 15 GB quota is full, and everything stops working at once.

Here's what to do — starting with free options and ending with the one that solves it permanently.

Why "15 GB" feels like much less

Google shares 15 GB across Gmail, Drive, and Photos. Not 15 GB each — 15 GB total. Years of email with PDF attachments, a few phone backups in Google Photos, and a couple of synced desktop folders can fill it without you noticing until everything stops.

Quick fixes (free, 10 minutes)

1. Find and delete large Drive files. Go to drive.google.com → Storage in the left sidebar. Files are sorted by size. Delete what you don't need — and then empty the Trash, or deleted files still count toward your quota.

2. Clear big Gmail attachments. Search has:attachment larger:10M in Gmail. Years of newsletters with PDFs, video files sent via email, and old backups often account for gigabytes. Delete and empty the Bin.

3. Compress Google Photos. In Google Photos → Settings → Storage saver, you can re-compress existing photos slightly (usually imperceptibly) and stop future uploads counting as much. This can recover several gigabytes if photos are the culprit.

The permanent fix: move files off Google

Cleanup buys time. If you want to stop getting the warning for good, the fix is to move files you want to keep to a different cloud — freeing the Drive space permanently without deleting anything.

Two services give you free storage to receive moved files:

• Mega.nz — 20 GB free, end-to-end encrypted
• Drime — 20 GB free, EU-based

Used together, that's 40 GB of free storage elsewhere — enough to empty a full Google account and reclaim the space.

How the transfer works with GTransfer:

1. Sign in at gtransfer.app and connect your Google account
2. Connect your Mega.nz or Drime account
3. Select the Drive files you want to move (sort by size to tackle the biggest first)
4. GTransfer transfers them directly, cloud-to-cloud — no downloading to your device
5. Once confirmed, delete those files from Drive and empty Trash — space is freed

The cost: GTransfer Pro is £19 once. Compare that to Google One at £1.59/month (£19/year, every year). If Drive files are eating your quota, GTransfer pays for itself in year one and costs nothing after that.

What if photos are the problem?

GTransfer moves Drive files, not Google Photos albums. If photos are your main storage culprit, the options are: switch to Storage saver quality in Google Photos (free, slightly reduced quality), pay for Google One storage, or manually download and delete old photo albums.
