Droffett

Droffett is a handy drop application utility for Mac that allows you to easily "flatten" any folder by moving all descendant files directly inside it. This is especially useful when dealing with complex folder structures or when you need to consolidate files into one place.

It's important to note that once you have flattened a folder, this operation is irreversible. Therefore, it's recommended that you manually make a backup copy of the folder before proceeding. Use Droffett at your own risk!

Another thing to keep in mind is that application packages, bundles, and other types of folders are also considered when flattening a folder. However, emptied folders are left intact, and folders themselves are not moved during the process.

To use Droffett, simply drag the folder you want to flatten onto the Droffett application icon in the Finder or the main window. The application will then prompt you to confirm that you want to proceed before beginning the flattening process.

By default, Droffett quits once it's done with the operation. However, you can use the "Preferences..." menu option to turn this option off if desired.

Overall, Droffett is an excellent tool for anyone who needs to quickly and easily flatten folders on their Mac. It's simple to use and can save you a lot of time and effort when organizing your files.
