I'm looking for this answer for long time, it is frustrating that I couldn't search my email by its size, because my mail box is full and I wanted to search those large size unwanted email and delete away. Anyone know this?

swamy you cannot search emails in gmail by size

Swamy,as far as I know there is no way to search eMails by size within GMail. You can, however, search for "has:attachment" to filter for all eMails with an attachment. If you are looking for a specific attachment, you could search for the filename, e.g. "filename:pdf"To sort your eMail by file size, you could import them from within Thunderbird or Outlook. Both programs have a sort by size (and many other criteria) option. This site explains how to import GMail eMails in Outlook 2003 and it works similar in Thunderbird: https://mail.google.com/support/bin/answer.py?hl...
