Belvedere

Keep your desktop or any other folder on your hard drive organized and under control with Belvedere, an automated Windows file management tool. Use Belvedere's friendly interface to create advanced rules to move, copy, delete, rename, or open files based on their name, extension, size, creation date, and more. Sets up rules for taking actions on files based on the name of a file, its extension, size, age, and more. Belvedere is a Windows knock-off of the Mac-only Hazel, so for a few good ideas for how you might get started with Belvedere, check out this guide. Belvedere's not quite up to par with Hazel yet, but in time we're hoping to implement as many of Hazel's features as we can for Windows users. Thanks to our friends at Lifehacker!
