Wing doesn't analyze files other than Python right now but it's not hard 
to write a script to open a file based on selection or click in the 
editor, which maybe is enough in this case.  I've appended below my 
signature code that you could paste into scripts/editor_extensions.py in 
your Wing installation to replace the similar code that is there in Wing 
4.1.7 (it assumes the imports in that file will be available to it, so 
would need those added if not in that context).  This adds opening also 
file names (the old code only opened urls) and will be in Wing 4.1.8.
