Is your Gmail inbox gone full of messages and you don’t know which emails are having large attachments and consuming your limited Gmail mailbox space? Since there are several ways including Google scripts that help you to locate your emails with larger attachment in your Gmail mailbox, but there is an easy way also with which you can discover your emails having specific size of attachment by typing in Gmail search box.
There is a new feature in Gmail called undocumented “size” search operator that makes it possible to find out all the big emails in the mailbox quickly and precisely whose size exceeds a particular threshold.
The syntax for this search is: size:[size in bytes]
For instance, Gmail search query like size:5242880 will list all big emails who size is 5 MB or greater while size:1048576 list messages that are bigger than 1 MB. If you feel uncomfortable to remember the size in bytes (1 MB = 104876 bytes) or your memory is little hazy, then to make things a bit easier to remember, you can also think of the number as 1 followed by 6 zeros.
Once you have found the large emails attachments that are taking too much spaces, you can either delete if they are of no use, or apply the #googleDrive label to directly save those attachments to Google Drive before deleting them from your Gmail mailbox.
