I know that sorting my Outlook e-mail into folders will keep my inbox neat and tidy. But I don't use my folders nearly as often as I should. It's not that sorting messages is hard or even all that time consuming; it's just that Outlook's process for doing so is not as streamlined as it could be. That's where Caelo Software's Single Click Filing for Outlook comes in. This $5 utility lives up to its name, allowing you to file multiple messages into your Outlook folders with a single click of the mouse.

You can add up to 10 folder shortcuts. Once they're added, you simply highlight the messages you'd like to store in the folder, and click the folder shortcut. That's it: your messages are automatically transferred to the folder. It's so simple, it's a wonder Microsoft hasn't thought of this itself.

Single Click Filing for Outlook serves the single purpose of filing your messages. You can't access your folders by clicking on buttons it adds to your Outlook window--something I kept trying to do before I got the hang of it. But what it does, it does very well.
