What's Wrong?

I'm unable to select a folder outside of my home directory.

Unlike MacOS, on windows it's common to have other drives to store data. Currently it does not allow me to select my projects folder on d:\Projects.
I tried a junction and a symlink and am unable to use either of those to get access to my projects folder.
It's too large to fit on my c:\ drive, and I can't mount it in my home directory like I could on MacOS. For windows this is prohibitively restrictive. I can understand preventing access to system directories, or preventing program files directories, but other drives should be fine.

This unfortunately makes Cowork non functional for many with this use case.

What Should Happen?

I should be able to select alternative drives on windows.
