Storage full: OneDrive, Gmail and iCloud explained

Free online storage is small, and photos fill it up quickly. When it's full, email and phone backups can quietly stop working. Here's how to find what's full and make room.

Free up Google storage (Gmail)

  1. Open the clean-up tool

    In a web browser, go to one.google.com/storage and sign in. Click Clean up space (or Free up account storage).

    Groups like "Emails with large attachments", "Spam", "Deleted items" and "Large files".
  2. Empty spam and bin

    Start with Spam and Deleted/Bin. These are safe to clear.

  3. Delete large old emails

    In Gmail, type has:attachment larger:10M in the search box and press Enter. Delete old emails with big attachments you no longer need. Then empty the Bin.

Free up Microsoft storage (Outlook.com / OneDrive)

  1. Empty deleted items and junk

    In Outlook.com, right-click Deleted Items → Empty folder. Do the same for Junk Email.

  2. Empty the OneDrive recycle bin

    Go to onedrive.com, sign in, click Recycle bin → Empty recycle bin. Deleted files still count until you do this.

  3. Check what's using OneDrive

    Often it's photos from a phone, or the computer's Desktop and Documents being backed up. Copy large things to a USB drive and check them before removing them from OneDrive.

    Files in the OneDrive folder on your computer are the same files as online. Deleting them in one place deletes them everywhere. Copy them to a USB drive first.

Free up iCloud storage (iPhone)

  1. See what's using it

    Settings → tap your name → iCloud → Manage Account Storage (or Manage Storage).

  2. Remove old device backups

    Tap Backups. If you see backups from old phones or iPads you no longer have, tap them and delete. This is often the biggest win.

  3. Photos

    Copy photos to a computer first (how), then delete ones you don't want. Deleted photos stay in "Recently Deleted" for 30 days: empty that album to free the space straight away.

Or pay for more space

If you'd rather keep everything online, a small monthly plan from Google, Microsoft or Apple is the simplest fix. Check the current price in your account settings before agreeing, and only buy from the company's own settings page, never from a link in an email.

Stop and get help if
  • You're not sure whether deleting something will remove it from other devices
  • Photos have gone missing
  • You get emails saying your storage is full with a link to "upgrade": check in your real account instead, as these are often scams
