When you try to issue a CD (Change Directory) to a LFN (Long File Name), you receive one of the following:

                                 Too many parameters                                 Parameter format not correct                                 Invalid directory
One reason could be that you are using Command.com.

Use CMD.exe.

Change your Command.com shortcuts to be CMD.exe shortcuts.

If you still receive the error, use either of the following methods:

1. Use the short name (Dir <Drive>\ParentFolder /x /ad).

2. Type CD \LFN or CD /D "<Drive:>\LFN".

3. Type Pushd \LFN or Pushd "<Drive:>\LFN".
