I use window vista version. I want to open a file using relative path.I  
wonder it is possible and how.

Thank you very much,

Check out the “require\_all” gem which has a require\_rel method.

or “require\_relative” from backports/1.9:

Also note that if you want to calculate a relative path between two  
files, use Pathname#relative\_path\_from
