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
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".
