From: Craig on
Haven't tried it but - Winderz only & F/OSS. Looks compelling:

> Windows only: 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.
>
> License: Belvedere is licensed under the GNU Public License. If you'd
> like to take a look at the source, head over to GitHub.
>
> What it does: Sets up rules for taking actions on files based on the
> name of a file, its extension, size, age, and more.
