I use File::join perfect on Linux, but when I use it on Windows, it  
still  
use “/” to separate file path rather than “”. Does it mean File::join  
can  
not be used on Windows?

Apart from the discussion indicated by Harry I use it frequently and  
without any problems either under cygwin, either under “pure” Windows  
Ruby.  
I always felt the purpose of File.join is to be multiplatform 😉
