TRINIX

I needed a handy tool that made certain directories acted like a separate drive.

After a bit googling i found this neat, free tool.

The tool explains itself. It works like Daemon tools, I allows you to set a Directory as a Virtual Drive.
You can save your dictories to these Virtual drives and  let  the drives be loaded during startup.

More info you ‘ll find on the website self. And of course this is TOTALLY FREE!!!
