I've only used Droffett a couple times, and it works as advertised just fine on my Mac OS X 10.2.8 machine. Seems to be one of those "do one thing and do it well" or at least "do it without crashing and causing immense annoyance" programs. Two additional features would make it more useful -- 1) if instead of just not moving files that have the same name as files already in the target location, it would rename the files in a user=configurable way, or even just by adding a number like a lot of other programs do in a similar situation; and 2) it would be great if it could optionally rename or add to filenames the name of each files enclosing folder. So if you've got a bunch of folders with, say, student names, and each contains a set of files with identical names like "test01", "test02", etc. it would be good if Droffett could add the folder names to those file names, so you would end up with the "flattened" collected files having names like "Smith test01", "Macy test 01", "Fritz test 01".
