If you use another Windows version, Linux, Mac or another supported operating system, then consult the documentation that is included with it or try to find the information on the internet using a search engine.

If the command you want to execute exceeds the limit of your Windows system and if the cause are long file or folder paths, you may use the DOS functions "subst" or "net use" as a possible workaround.
