Double quotes allow variable substitution (at least), so if there's a "$" in 
the pathname you're gonna have problems. Names with "$" in them were very 
popular in DOS, for example.

Single quotes should be used whenever you don't want any expansions to be done 
(i.e. for the string to be treated verbatim).
