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 directoryOne reason could be that you are using Command.com.
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".
