I have a Windows11 box and an Android phone. If I stick a USB cable

got).
I am reasonably sure that in Windows10 it *was* a mount point, and I had
no problems with access.
I'm still running Windows 10 and the behaviour there is the same for
me, so I don't think it's a 10/11 thing. I think a loooooong time ago
some Android devices used to do what you describe, but I haven't seen
it recently, they all seem to use the nasty MTP mode now. I'd also be
curious to hear if others have had different experiences though.
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 .
