Is it possible to access a USB drive or Flash card without using the drive letter that Windows assigns it? I thought I read somewhere that the Volume GUID or something can be used but will that allow me to open it up in explorer once I identify it? The reason this is important to me is because there may not be enough drive letters to handle the number of drives so I want to be able to still access them.
Use MOUNTVOL by itself to get the drive ID.
Here you go:
MOUNTVOL C:\USB: \\?\Volume{ebc79032-5270-11d8-a724-806d6172696f}\
OR Winkey+R (Start-Run) \\?\Volume{ebc79032-5270-11d8-a724-806d6172696f}\
