open the command prompt on your computer
on windows it's cmd.exe, also known as "command prompt" I would also try out "Windows Terminal" it's a pretty good option, looks a bit more modern with more features like tabs and shortcuts
now stare at it. love it. kiss it. she's you're new friend and you're gonna be nice to her.
the first and only command i will tell you about is "cd", change directory. this opens a folder. try "cd C:/Users/[your user]/Desktop" ypu cam press "tab" autocomplete folder names, or cycle through options. on windows it is not case sensitive
the command prompt will likely already open at the "C:/Users/[username]" folder, so you could also type "cd Desktop". the current folder you're im will always be written before a right chevron ">" before place where you can type.
advanced (/j) technique: if you want to change directory to another drive, like if you have a secondary drive, or a flash drive plugged in, or anything else, you can do "cd -d D:/testfolder".
"-d" means you're specifying a folder on a different drive
practice by using file explorer to navigate to a random folder on your computer, then going to the same folder in the command prompt. if youve got this down, congrats, thats 90℅ of learning how to use cmd. the rest, the program that needs cmd will usually tell you how to use it step by step, in the readme.
