I've searched for this all over the web and can't find any
answer, either positive or negative, so I'm asking it here.
Do you know if there's a way to open a folder with the OS's
"explorer", such as Finder on Mac or Explorer on Windows? If so,
An other question would be: is it possible to open a file
(say, a JPG image) with its associated program (eg. XNView )?
