Field notes
The utility groups macOS file associations into categories or reusable profiles, with examples spanning code extensions, office documents, images, and local HTML files. Its Router Mode is described as taking over a file type after one confirmation, while browser handling remains separate for web links. The site also states that profiles can be imported and exported and that the app works offline after licence entry.
