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.
