Using Command line tool programmes

[Plamz Doom]

No experience with command line tools or how to use them but if i want to extract stuff from games like the wii version of Revenge of the Fallen (Krome Studios .rkv file format) and Metroid Prime 3 Corruption (Retro Studios .pak file format) i will need to know how to use these specific command line tools. i have no idea or experience with command line tools so all this might sound dumb but i need to know how to use these programmes becuase launching the .exe doesn't do anything and trying to follow the vague instructions they have and applying them to Command Prompt and Powershell doesn't work either so i'm completely lost.

You should first navigate to your working directory using cd. Then you can follow the instructions for those tools.
