[Pharo-users] Which is the best way of opening a PDF and HTML local files from Pharo

Hi, I'm trying to open some local files from Pharo. They're in PDF and HTML format. I thought that I could use WebBrowser, so it can delegate to the browser opening the files, without any other requirement, but is not working. There is a better way to open such files from several platforms? Cheers, Offray
