Where is my file?

I have a file whose name is


on my Windows machine

I have attempted to open this file (which I know exists) in my
controller using a variety of names to no avail.

How can I open this file in both my development environment (Windows &
webrick) and on my server (Linux abd Apache(?))




What do you mean by 'open this file in my controller'? Show us some code.

If you are trying to view it in a browser or redirect to it, it would
be the third one (/documentation/....).
