I have to work on the same code and folders on different computers (one at work and possibly more than one at home).  
 All what I need is a simple way to:  

* have three (or more) folders (one on each computer and one on the usb pen drive) all synchronised with each other
* deal with them using eclipse only (no git, if possible, or, at most, an elementary use of it)
* handle the whole workspace (source, libraries, other note files, ...).  

I have already found similar questions but I still don't get from the answers what can be easily done to get the result.
