Gmail attachment cleanup. Cleanup large gmail letters

Even though Gmail gives you quite a lot of storage, for years I have developed a habit to clean up the trash. It just feels right.

Type in "size:20000000" for filtering mails with attachments >20MB. Seach query is in bytes, filter by any size limit you want. "size:5000000" for emails with larger then 5MB attachments.

Once you find the monstrous mails - you can either delete it all or just one of the messages. If you open the conversation - large messages are always expanded. This is just great if you have some development material which is out of date, but you would still like to save the conversation for later. Just select "Delete this message" from message tools.
