Sync with folders? Interesting if possible :D

Hey everyone,

I was just wondering if anyone has a way or a tool in mind that can do the following -->

Sync a folder on a USB stick with the folder on the PC.

Basically........ lets say I have a folder named 'work stuff' on my PC and the same content and folder on my USB. Then I go and change/add/edit to the PC one but not the USB.

Then, is there a way that when I connect the USB, it will search for the same folder name and sync all the files so that the PC and USB versions are the same??? Without me having to manually keep updating both.

Would be great if there is a way to do this!

Thanks!
