The Command Prompt has a handy little feature that lets to change directory paths using autocomplete. To change to a directory or type a directory name, you can type the starting letters of the directory and press the TAB<\/kbd> key to autocomplete the file or folder path.<\/p>\n

(To learn how to use TAB autocomplete in Command Prompt, check out the examples<\/a> provided at the end of this article.)<\/em><\/p>\n

File and folder paths autocomplete feature is enabled by default in Windows 10. But if it stops working for some reason, this article tells you how to fix it.<\/p>\n

How to Enable Command Prompt TAB Autocomplete<\/h2>\n

To enable the Command Prompt to autocomplete file and folder paths upon pressing the TAB<\/kbd> key, follow these steps:<\/p>\n

    \n
  1. Start the Registry Editor (regedit.exe<\/code>)<\/li>\n
  2. Go to the following branch:\n
    HKEY_CURRENT_USER\\Software\\Microsoft\\Command Processor<\/pre>\n
    (The user-specific settings under HKEY_CURRENT_USER<\/code> take precedence over the machine settings. So, you don’t need to repeat the setting under the HKEY_LOCAL_MACHINE<\/code> branch.)<\/div>\n<\/li>\n
  3. Double-click CompletionChar<\/code> and set its data to 9<\/code><\/li>\n
  4. Double-click PathCompletionChar<\/code> and set its data to 9<\/code>\n
    If the above registry values are missing, you’ll need to manually create the values (of type DWORD 32-bit) and set the data. Note that the value 9<\/code> (0x9<\/code>) is the ASCII key code for the TAB<\/kbd>\u00a0key<\/kbd>.<\/em><\/div>\n<\/li>\n
  5. Exit the Registry Editor.<\/li>\n
  6. Close and reopen Command Prompt for the change to take effect.<\/li>\n<\/ol>\n
    (Using command-line)<\/h3>\n
    Alternately, to enable the Command Prompt TAB<\/kbd> Autocomplete feature via command-line, use the following reg.exe<\/code> commands from a Command Prompt window:<\/p>\n
    reg add \"hkcu\\software\\microsoft\\command processor\" \/v CompletionChar \/d 9 \/t REG_DWORD \/f\r\nreg add \"hkcu\\software\\microsoft\\command processor\" \/v PathCompletionChar \/d 9 \/t REG_DWORD \/f<\/pre>\n
    Close and reopen Command Prompt for the change to take effect.<\/p>\n
    Important:<\/strong> If you start the Command Prompt using the CMD.EXE \/F:OFF<\/code> switch, auto-completion using the TAB<\/kbd> key won’t work, as the \/F:OFF<\/code> switch it overrides the registry settings.<\/p>\n

    Typing the complete folder path manually is an annoying task. The Command Prompt file and folder name autocomplete feature is convenient, especially when dealing with long folder names or when the folder names have version numbers<\/a> in them.<\/p>\n
    \n
    <\/a>Tips: How the Command Prompt TAB AutoComplete works<\/h3>\n
    For example, to change to the directory named Program Files<\/code>, from the C:\\<\/code> prompt, simply type cd prog<\/code> and press the TAB<\/kbd> key. The Command Prompt autocompletes the directory name automatically. The autocomplete feature automatically encloses file\/folder names in double-quotes if it contains one or more spaces.<\/p>\n
    Cycle through folder names using TAB<\/h4>\n
    However, if there are multiple folders whose name start with Prog<\/code> — then pressing TAB<\/kbd> once will autocomplete the first folder name that begins with Prog<\/code>. Subsequent TAB<\/kbd> presses will cycle through the remaining matching folder names.<\/p>\n
    For example, you have three folder names that start with Prog<\/code> on the C:\\ drive — Program Files<\/code>, Program Files (x86)<\/code> and ProgramData<\/code>. Let’s say you want to switch to ProgramData<\/code> on the C:\\<\/code> drive using the autocomplete feature.<\/p>\n
