I'm looking for a program that I thought for sure would exist, but I'm having difficulty tracking down.

What I want is pretty straightforward: a program that will watch a folder, and when it sees something in that folder it moves it to another folder or multiple folders.

Basically I'm looking for Dropbox for local file organization, and also I don't want to copy the files, just move them entirely.

Is there something that will do this on Windows?
