Active Directory

Hello
I am attempting to follow a tutorial on creating a simple Vue.js structure in WP.

It contains a statement,
After you have installed these two dependencies, you need to change the active directory to your local WordPress instance’s wp-content/plugins directory

Now I am usually ok with finding answers but all I get is Active Directory Integration results, none of which appear to be the answer.

I am ok with navigating file structures and have amended wp files previously, but am at a loss to understand the “change active directory” part.
Any assistance is appreciated here.
