It’s usually a good idea to make a back up of a file before doing something drastically with it. For example if we had an executable called matt.exe that we were going to upgrade we should copy it to another directory and make a backup of it first. See script 2. Copy c:\windows\matt.exe c:\temp. Ren c:\temp\matt.exe c:\temp\matt.bak ................
