Q: My company recently upgraded my Windows 2000 workstation to Windows XP Professional Edition. Since the upgrade, I've lost the ability to use the Tab key to automatically complete filenames and directory names from the command line. Can you help me get this capability back?
Sure thing. The feature you're referring to is called filename and directory name completion and is indeed very handy. It's so handy that it's the first customization I make to the command processor on every new workstation I build.
There are a couple of ways you can enable filename and directory name completion:
You can enable or disable the feature for a particular instance of cmd.exe. Use the /F:On command-line switch to enable the feature and the /F:Off switch to disable it.
You can enable the feature for all instances of cmd.exe, which is my preference. Configuring name completion this way requires a registry change. Open the registry editor and go to the HKEY_CURRENT_USER\Software\Microsoft\Command Processor subkey. Change the CompletionChar's Data value to 0x9, which is the hexadecimal value for the Tab key. You need to start a new instance of cmd.exe to see the change. Alternatively, you can change the CompletionChar value in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor subkey. However, be aware that the CompletionChar setting in the HKEY_CURRENT_USER subtree will override any CompletionChar setting in the HKEY_LOCAL_MACHINE subtree. . . .
