Hello Samit,

We appreciate your query.

By the looks of it, I believe that you are referring to the steps to copy a folder structure in macOS; specifically Step #4. If yes, then here is some clarification:

Yes, you need to drag and drop the source folder into the Terminal window. Once done, drag and drop the destination folder into the Terminal window.
This will automatically insert the source’s and the destination’s path into the command, after which you can press “Enter” to run it.

Since macOS is a Linux-based OS, it uses a similar syntax when running commands. If you can compare the commands for Linux and macOS above, you will notice that they are similar, except for the source folder path and the destination folder path. These are given by dragging and dropping the folders (in the case of macOS).
