I read bazillion questions on similar topic but they always mean "PSCP" when saying "PuTTy". The thing is I am in an environment where I am not allowed to use anything else than either PuTTy or WinSCP. And I want to copy files in a script.
I was told that this can be done using commands in a file that can be passed to PuTTy. And that this solution does not open another connection, but rather uses the one already opened by putty.exe. (I can not connect from outside to my working PC, so I can not start scp on the remote server to push files to my disk.)
