Windows XP's command prompt completes file/folder name when u press tab key. Windows 2000 by default doesnt provide this feature. But its there and u need to enable it from registry. Follow the steps below:
1- For one thing, Make sure you run "cmd", not "command" to get to the command shell 2- Go to Start / Run - "regedt32" 3- Go to the window: "HKEY_LOCAL_MACHINE on Local Machine" and find "Software\Microsoft\Command Processor" 4- Change the key "PathCompletionChar" to 9 5- The next time you fire up a command shell, you will have tab completion
