You need to use old DOS commands, like "cd", (without the quotes), meaning, "change directory".
eg; type in cd.. (note the two full stops immediately after the d)
C:\Documents and Settings\Jack> cd.. - press Enter takes you to
C:\Documents and Settings\>
Type in cd.. again to get you back to c:\>
You can type in "help" at any stage for a list of commands, or help command (eg help cd) for help on each command.
I hope that helps.
All those words start with the same letter, genius. Except for the first one.
When I open command prompt already written in the window is C:\Documents and Settings\Jack>
It doesn't let me delete this, the only way I can get it to just say C:\> is by using the open command window here powertoy for windows.
