Many Android versions ago, Android changed the way it shared its 
internal disk to the computer over USB from acting like an USB stick 
with a FAT file system to acting like a "Multimedia shared storage" 
(MTG?) device.  This in turn caused it to be mounted differently in 
operating systems, including Windows.

Folders that show up in Windows File Explorer may be actual folders 
available via the Windows File IO APIs, or they may be virtual locations 
implemented in loadable File Explorer extensions such as the extension 
that allows using File Explorer to navigate inside ZIP files.  If (and I 
don't know if this is the case), the Windows handling of the MTG? USB 
protocol is an File Explorer extension, it probably isn't exposed to 
other software such as Cygwin or even cmd.exe .
