The command processor, CMD.EXE automatically defines the CD environment variable. Open a CMD.EXE window and type CD /D "%UserProfile%\My Documents" and press Enter. Then type @echo %CD% and press Enter to display the current directory.

If you wanted to go to the parent folder, type CD .. and press Enter.

If you wanted to script a process that displays the current directory, and each higher parent folder, until the root of the current drive is displayed, you could use the following script:

@echo off
:loop
@echo %cd%
if "%CD:~3,1%" EQU "" goto finish
cd ..
goto loop
:finish
If I open a CMD.EXE window and set the current directory using CD /D "%UserProfile%\My Documents", and then run a batch file that contains the above script, the following is displayed:
C:\Documents and Settings\Jerry\My Documents
C:\Documents and Settings\Jerry
C:\Documents and Settings
C:\
