Hello. I am trying to add a feature to an application I am working on that requires the user to select a drive on their system. I would love to just have a combo box with every active drive letter in it, however, I can't come up with way to do this.

If anyone has any suggestions it is appreciated.

P.S. I have Developer for the Steam version, I just haven't linked it yet to this account. Developer only solutions are valid.
EDIT: I linked them (still clueless on my issue though)

EDIT2: Thinking a bit creatively, I realize I can do a brute force test by checking each drive Letter A-Z to see if it is a valid directory at the start of the frame. If anyone has a better option feel free to post.
