The default home directory is /home/user (where "user" is the username), sometimes shortened to "~".
Profile
Domain Users.
Use the 'cd' command without any target; that always puts you in the home directory which becomes by default the working directory.
Users folder
By Default, Users have limited user rights to make most system changes. However, Guests are VERY limited than regular users.
User
The HOME environment variable has this information.
Profile
Each user (on a multi-user computer) has a home directory, and it is the first directory shown after a user logs in. For instance: rodney@downstairs:~$ shows that my user name is rodney, my host or computer name is 'downstairs', the tilde '~' shows that I am in my home directory, and the dollar sign '$' shows that all is ready for me to type in a command. Typing the command 'pwd' (without the single quotes) in a terminal will show which directory you are in - pwd means 'print working directory'. The command 'ls' will list all directories.

The root directory is the top level directory of the entire file system. Every branch starts from there. The current working directory is where you happen to be in the tree at the moment. If the root is always "/" and my process is in the directory /usr/local/bin/test/data, then the root directory is still "/" and my working directory is currently /usr/local/bin/test/data
