Droffett is a drop application which "flattens" a folder, i.e. moves all files which are descendants of it so that they are directly inside it.
Droffett can also be used to aggregate a set of files by extension. This process will place all files with the same extension into a folder named after that extension. Specify this option using the Preferences window.
Droffett is very easy to use.
How to use Droffett: Simply drag a folder on top of the Droffett application icon in the Finder or the main window. Processing commences immediately.
Use the Preferences window to specify various options (see below.)
