Given the above summary, write a detailed text in English for it.
Make sure you include the space after "cd". This command, which stands for "change directory", is the root of any directory change. Don't press the ↵ Enter key. A directory path is like a map to a specific folder. For example, if the directory to which you want to change is the "System32" folder that's in the "WINDOWS" folder on the hard drive, the path would be "C:\WINDOWS\System32\". You can find a folder's path by opening My Computer, double-clicking the hard drive icon, navigating to your destination, and then looking at the address at the top of the folder. Your command or address goes after the "cd" command; make sure there is a space between "cd" and your command.  For example, your whole command might look like cd Windows\System32 or cd D:. Since your computer's default directory location will be the hard drive (e.g., "C:"), you don't need to type in the hard drive's name. Doing so will change the Command Prompt directory to your selected one.
