Yeah

Windows/DOS has accepted either / or \ as directory separators for a while:

However as you said dir is an internal command and forward slash breaks with
it on the windows command line, but it does work in irb and stand-alone
ruby.


irb(main):001:0> system('dir "d:/program files"')
 Volume in drive D is WINDOWS
 Volume Serial Number is 847A-A69A

 Directory of d:\program files
