DOS COMMAND

Hi,
this might be easy but i dont know it.
how can i access the Program Files directory through the command utility ( DOS COMMAND) As you all know this directory has long name and DOS does not accept long names.
When i try to move to that directory as
“C:\ cd Program Files ” i get the following ” too many parameters -files”

Actually i am writing a batch file to copy some files from the network to the users PCs. some of these files should be copied to the ProgramFile directory. Thats why i need to know how to move to that directory using the dos command.

your help is appreciated
