Automatic Downloads sorting
Boo monitors Downloads in the background and sorts files automatically after they land there, so you do not need to drag them into folders yourself.
Boo
Boo is a Mac menu-bar app that watches your Downloads folder and automatically sorts files into the right place. It learns file-type destinations, remembers them, and leaves you with a cleaner Downloads folder.
Overview
Boo is a tiny Mac menu-bar app that watches the Downloads folder and sorts incoming files into the right places. Its job is simple: reduce the pile-up in Downloads without making you maintain rules up front.
The product is designed around a low-friction workflow. Known file types are moved automatically, new types are handled once through a prompt, and Boo remembers the choice so the same kind of file goes to the same place next time. The site also presents Boo as free, open source, and MIT licensed, with source code available on GitHub.
Features
Remembered file-type destinations
After Boo learns a file type once, it reuses that destination the next time it sees the same type and does not prompt again.
One-time setup for new extensions
For an unknown file type, Boo prompts you once to choose a folder or create a new one, then saves that choice for future downloads.
Leave files in Downloads
If you prefer to keep a file where it is, Boo lets you leave it in Downloads instead of forcing a move.
Native open-source app
The site says Boo is native, open source, MIT licensed, and built with Swift and SwiftUI, which makes it easy to inspect, fork, theme, and extend.
Use Cases
Hands-off Downloads cleanup
Useful for people who want their Downloads folder cleaned up automatically after every download, without building a manual folder rule set first.
Repeated file-type sorting
Helpful when you regularly download the same kinds of files and want them sent to the same destination without repeating the same decision.
Learning new file types
Good for users who are still deciding where a new file type should live, because Boo asks once and then remembers the answer.
Selective file handling
Appropriate for people who sometimes prefer to keep a file in Downloads, since Boo allows files to remain there instead of forcing a move.
