I don't quite get it. With programs like Subversion, files are stored in the repository but when you want to use it, it's checked out and then stored on a local drive.
With this, it seems the file is only ever in the 'repository' ie workspace. So, here's my problem...
Say I have a file like something.bmp which I've added to the workspace. Now I want to edit it. But right-clicking or double-clicking and opening opens (on my computer) Microsoft Viewer. So how do I edit this file? With Microsoft Explorer I could right-click and select a different program. Should I keep a duplicate folder structure with the original file to edit it, and then add it back into the workspace each time? I doesn't automatically update the file if I do so that makes little sense, but without the original file I can't edit it?
I am missing something? Am I totally out to lunch here?

thanks...
