did you look at http://www.dropitproject.com/
freeware including au3 source
from their site:
When you need to organize files, DropIt can eliminate much of the drudgery of searching and manually opening folders and moving files around.
Drop a group of different files and folders on the floating DropIt image and it sorts them to defined destination folders, compresses or extracts them, opens them with associated programs or performs other defined actions.
You can define how to filter your files (by name, directory, size, date, properties, content, regular expressions) and associate one of the 20 available actions to perform (Move, Copy, Compress, Extract, Rename, Delete, Split, Join, Encrypt, Decrypt, Open With, Upload, Send by Mail, Create Gallery, Create List, Create Playlist, Create Shortcut, Copy to Clipboard, Change Properties and Ignore). You can also organize your associations in profiles and automatically scan monitored folders at a defined time interval to process included files.
instead of the big icon, you can also integrate with SendTo in context menu (see Options).
(please note there are some interworking problems with programs like gridmove and smallwindows)
