If you use Windows XP Command prompt either for small or large tasks, one feature that is not enable by default is Automatic Completion. This feature will complete file and folder names automatically that you type at a command prompt and is real handy with folders that have a space in its name…

   
You can activate or deactivate this feature for a computer, or for only the current command session.

To activate Automatic Completion for the current session, open a Command prompt and type cmd /f. To use, type CTRL+D to complete a folder name or CTRL+F to complete a file name.

CTRL+D

The folder Documents and Settings will auto complete (with quotes since a space is included) and you can just press enter to change to the folder.

To display the contents of a text file, such as example.txt, you can type

type:exa

If you enable Automatic Completion permanently, the feature is available to all users. However, you can deactivate the feature for any individual user, or you can use different control characters for that user than you applied to the computer. The user settings take precedence over the computer settings.
