A. You can set the registry entry HKEY_CURRENT_USER\Software\Microsoft\Command Processor\CompletionChar to 9 and use the Tab key to enable filename completion. However, you can use another setting to enable path completion (but not filename completion). To do so, complete the following steps:
- Start the registry editor (regedit.exe).
- Move to HKEY_CURRENT_USER\Software\Microsoft\Command Processor.
- From the Edit menu, select New, then DWORD value.
- Enter the name PathCompletionChar.
- Double-click New Value, and set the value to the desired key (4 sets to Ctrl+D).
- Click OK.
- Close the registry editor.
You don't need to restart Windows; just start a new Command Prompt window (cmd.exe).
