Extraction: Extract files from main .exe to get setup.exe and the rest.

Notes: use /r /f1”c:\setup.iss” to create the setup.iss in your C:\ copy setup.iss file in the same directory where your application setup.exe file resides in.

I do not understand how to create the setup.iss with these instructions. what baffles me is the use /r /f1”c:\

How can someone explain to me simplier.
