Cleaning Out Gmail Without Losing Important Files

Your Google storage is shared across Gmail, Google Drive and Google Photos, so clearing out old email frees up space everywhere. Do it in the right order and you keep every file you actually need.

Instructions

Work through these sections in order. Saving what you need comes first, deleting comes last.

INFO: Deleted mail sits in Trash for 30 days and still counts against your storage. You only get the space back after you empty Trash.

Know what a delete actually removes

Two kinds of files show up in email, and they behave differently:

  • Attached files live inside the message. Permanently deleting the email deletes the attachment with it.
  • Google Drive links—Docs, Sheets, Slides or files inserted as a Drive link—live in Drive. Deleting the email does not touch the file, but you also free up almost no space by deleting those messages.

If a Drive link points to a file someone else owns, open the file and star it or add a shortcut to your Drive before you delete the email. That keeps a path to the file once the message is gone.

Save the attachments you want to keep

  1. Open the message and hover over the attachment preview.
  2. Click Add to Drive to save the file to Google Drive, or Download to save it to your device.
  3. Confirm the file is where you expect before you delete the email.

WARNING: Saving an attachment to Google Drive moves the space, it does not free it. To reduce your Google storage, save the file to your device or to OneDrive, another storage option the University of Maine System provides.

Find the email worth deleting

Type any of these into the Gmail search box:

  • has:attachment larger:10M—large attachments, the fastest way to reclaim space
  • older_than:2y—mail you have likely moved past
  • in:spam—spam counts against your quota
  • from:sender@example.com—newsletters and bulk senders, one source at a time

Delete and empty Trash

  1. Run one of the searches above and review the results.
  2. Select the messages you no longer need and click Delete.
  3. Go to Trash → Empty Trash now.
  4. Repeat in Spam.
IMPORTANT: Emptying Trash is permanent. Nothing is recoverable afterward, so review the messages before you confirm. Storage totals can take a while to update.
