I'm a designer using a Mac with Dreamweaver CS3 to design pages on a web app. The team I work with is using Microsoft Visual Studio to manage projects, check files in and out, etc. Each of us has a MS Windows Server 2003 with a local copy of the site.

I only use Visual Studio to manage the project by checking in and out, and managing the project files because the Mac has a large display and is my primary computer.

I was wondering if there was a way I could check files out so my team members see them as locked when I'm editing them, and vice versa in Dreamweaver on my Mac.

How do I set up my site in Dreamweaver to do this?
I don't think I want to set up the site as an FTP. What's an RDS?

In the DW setup for each site there is a Check In/Out function, it's under Manage Sites. Your colleagues will see an LCK file for each file you have checked out.
