With the advent of downloading audio/video/ebook files from torrent and other means, I wonder if there are any powerful file watcher app out there that detects, filters, execute rule engine and determine which action needs to be executed to every detected files.
For e.g put tv series in a folder, clean up file name using regex. move audio files and import into itunes. etc.
I know I can write this kind of simple app myself, but just wondering if there's already exactly the same app out there that does the same thing. Extra point if it had a strong community behind it sharing rules and action.
Belvedere  is another tool you might want to have a look at. Haven't tried it myself though and maybe not as versatile as you want. http://lifehacker.com/341950/belvedere-automates-your-self+cleaning-pc
