### Anything else?

scp cygwin version does not understand the command line. It seems that SCP doesn't understand the path "c:\Users\CHRIST~1.MER\AppData\Local\Temp\vscode_server_1718954948470\vscode-cli-611f9bfce64f25108829dd295f54a6894e87339d.tar.gz".
It seems that scp only support path with /cygdrive/c......

A solution could be: move to the current directory of the file, then use local path vscode-cli-611f9bfce64f25108829dd295f54a6894e87339d.tar.gz

What do you think about that
Thanks
