    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 filter your files (by name, directory, size, date, properties, content or regular expressions) and associate one of the 21 available actions to perform (Move, Copy, Compress, Extract, Rename, Delete, Split, Join, Encrypt, Decrypt, Open With, Print, 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.
