## 4 Steps to clear space in Gmail

Although Gmail has 15 GB of space, it can run out of space quite fast, especially nowadays many emails contain attachments that can be quite large.

To free up space on Gmail, I usually do the following 4 steps:

## 1) Search “size:100k older:2018” on Gmail

The above searches for files 100 kilobytes or larger, dated 2018 or earlier.

You can modify your search accordingly, for example “size:1M older:2017” searches for files larger than 1 megabyte, older than 2017.

## 2) Search “from:facebook.com”

The above searches for all email sent from email address ending with “facebook.com”. This can be quite effective, since many small emails typically end up being larger than 1 single big email.

You can modify your search accordingly, for example “from:twitter.com”, etc.

## 3) Delete unwanted emails (found using methods above), and clear Trash

Clearing trash is important (otherwise the deleted files will still take up space). Messages that have been in Trash more than 30 days will be automatically deleted though.

Double check before you delete, since once deleted it is not possible to recover the emails.

## 4) Refresh your browser, and see that you have more space!

Typically, by using the above steps, I can delete up to 1o0 MB of email.
