Hi,

Just for a bit of context, Windows supports Cloud synced files via
Cloud Storage Providers 
(https://learn.microsoft.com/en-us/windows/win32/shell/integrate-cloud-storage)

The main one is OneDrive, I also use NextCloud, but regardless, the
issue I describe applies to both.

If I connect an SSH session via the "native" OpenSSH instance
integrated into Windows, I can do something like the following to a,
at the time, online only, not yet downloaded file, and OneDrive will
download it ahead of outputing it:

   shaddy@PUTER-MSW U:\UserData\shaddy\OneDrive\Documents>type DxDiag.txt
   <content follows>

But if I connect an SSH session via the Cygwin instance running on a
different port to 22, it does not trigger the provider to download the
file, and I see this error:

   shaddy@puter-msw 
/media/noacl/emulateduuid/UserData/shaddy/OneDrive/Documents
   $ cat DxDiag.txt
   cat: DxDiag.txt: Permission denied

The fact that the native SSH session is OK suggests to me that there
is some newer type of security token that that service obtains that
the Cygwin SSH service does not. But I've not looked into it too hard.

Just reporting this for now. It's not something I need to do
daily. Just an observance.
