Using Parallels Desktop 11 with a Windows 10 guest OS and I've set up a Custom shared folder in the Parallels config controls (while Windows was shut down) and see my new share in Windows Explorer with its new Drive letter V: Great. But when using the Windows CMD when I attempt cd V:\ I get the error above. I've googled and searched the forums but cannot find a similar problem. I use Parallels to run different OS and servers and I need to mimic a Windows apache server but my code is on the Mac. How to get Windows Apache to find this drive letter?
