Droffett 1.1

Droffett is a drop application which "flattens" a folder, i.e. moves (or aliases) all files which are descendants of it so that they are directly inside it. (See accompanying screenshot for illustration.)
Droffett can also be used to collate a folder 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.
