MS Windows
Setting up your Windows computer.
Make sure you can see the complete file name, including extensions (the part of the file name after the . , like .jpeg). To show all filename extensions on Windows, look here.
OK, gonna level with you here. I rarely use Windows, and don't have a lot to say about it. It's perfectly possible to do the kind of stuff we focus on at NSCAD on Windows computers, but I'm afraid you'll be pretty much on your own as far as detailed technical support.
You might find it a bit lonely here. Best of luck.
