I think you should be. I have a bunch of projects, although I sort of cheated. I have ‘1 project’ c:\github.com
And in there I have sub folders for each project (with their own GitHub Repos). Mostly so I can see different projects and go back and forth. But even without that you can with giving permission to view outside your projects folder I think?
WARNING: That increases risk as you are giving AI access to other folders. Although
that other solution you found looks like it would do the trick. Did it work?
