SUMMARY
This article describes how to configure Windows XP to complete file and folder names automatically that you type at a command prompt. This feature works by typing a control character that invokes the feature.

To Activate Automatic Completion
For example, to change to the Program Files folder, you can type cd \pro. Or, to display the contents of the Myfile.txt file, you can type type myf. If there are multiple folders or files that match the characters you type, typing the control character again displays the next matching instance. When the correct folder or file is displayed, press ENTER to complete the command. If no folder of file matches the characters that you type, you hear a beep.

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

To Activate Automatic Completion in the Current Session
To activate automatic completion for the current command session, type cmd /f. Then type CTRL+D to complete a folder name or CTRL+F to complete a file name.

To deactivate automatic complete, type cmd /f:off.

To Activate Automatic Completion Permanently
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.


 * 1) Click Start, click Run, type regedit, and then click OK.
 * 2) To enable automatic completion for the computer, locate and click the HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor key.
 * 3) To enable automatic completion for the current user, locate and click the HKEY_CURRENT_USER\Software\Microsoft\Command Processor key.
 * 4) For folder name completion, double-click the CompletionChar value. Type in hexadecimal the control character that you want to use.

For example, if you want to use the TAB key as the control character, the control character is 0x9 (type 9 as the value; Windows converts it to hexadecimal). If you want to use the same control characters that you use for a single command session, type 0x4 for CTRL+D and 0x6 for CTRL+F. You can use the same control character for both folder and file name completion.
 * 1) For file name completion, double-click the PathCompletionChar value. Type in hexadecimal the control character that you want to use.

For example, if you want to use the TAB key as the control character, the control character is 0x9 (type 9 as the value; Windows converts it to hexadecimal). If you want to use the same control characters that you use for a single command session, type 0x4 for CTRL+D and 0x6 for CTRL+F. You can use the same control character for both folder and file name completion.
 * 1) Quit Registry Editor.

If you enable this feature for the computer, 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.

Additional Information
Note the following differences between folder and file name completion:
 * The file name completion feature works on folders also because the feature searches for a complete path and matches against both file and folder names.
 * If you use the file-completion control character with a command that works only with folders (for example, the cd or rd command), only folder names are searched.
 * The folder completion feature matches only against folder names. This makes the folder completion feature faster for folder searching than the file name completion feature if there are both files and folders with matching strings.
