I downloaded pscp.exe to my computer and tried to set the PATH environment variable so that in the Command Prompt I would only have to type pscp. That way I wouldn't have to always type the full path the pscp.exe. So i went into my System | Advanced | Environment Variables. In the System variable box I selected Path and clicked Edit. At the end of the list I added C:\pscp.exe Then after clicking "ok" out of that I restarted my computer. Now in Command Prompt when I type pscp, I get the following error: 'pscp' is not recognized as an internal or external command, operable program or batch file. How do I set it so that I only have to type in pscp, no matter what directory I am in?

Try setting the path in autoexec.nt.
