SpeedFiler does one thing, and it does it well. The Outlook Add-in gracefully extends Outlook's filing command (Ctrl Shift v) with a smart window that narrows your folder list as you type. This means you don't have to go searching for the appropriate folder by scrolling through a huge list of folders. Just typing in the folder name on SpeedFiler toolbar and optional folder names will begin to autopopulate.

SpeedFiler can also be setup to request a folder for sent mail, every time you send a message it'll go in the folder. If you want to check it out, you can download a trial copy, valid for 30 days. To purchase, SpeedFiler will set you back $19.95
