IMAPSize is a freeware Windows application that allows you to quickly and efficiently manage your IMAP mail accounts. It is not another mail client. The main purpose of IMAPSize is to locate space consuming folders and allow you to manage them, hence putting your storage quota under control. To accomplish this task IMAPSize offers a variety of useful (and some unique) operations.

To accomplish this task IMAPSize offers a variety of useful (and some unique) operations.
You can perform many of the tasks that IMAPSize offers through some of the better email clients that support IMAP (e.g. Mulberry, Becky! and Thunderbird), however with IMAPSize you can do more maintenance tasks in far less time, since IMAPSize concentrates on providing means for maintaining your IMAP accounts, rather than using them.

If you are using an IMAP client that offers less features than the main players, you will find IMAPSize very handy (if not necessary...). IMAPSize also offers some features not found in other clients (e.g. the attachment deletion area, incremental backups, etc).
