I’ve been using Gmail for a few years and I finally got around to tidying up my email archive. This was becoming an issue as I keep a local backup of my Gmail account using IMAP Backup.
I wanted to delete messages with large attachments resulting from emailing work in progress. While you can find attachments using search modifiers has:attachment and filename:zip, you can’t search or sort on attachment size.
The solution: the IMAPsize freeware Windows IMAP utility found via this blog post from Amit Agarwal. IMAPsize’s speciality is searching your Gmail account for folders (Gmail labels) and messages based on attachment size.
I quickly found and deleted my large attachments using IMAPsize. Backup problem solved. Recommended.
