This is not a Dynamo question, but i wondering if someone in here can help 
Im setting up help links to files and directorys in my company template using the URL parameter. This work well for Pdf, excel, word
But when it comes to .rvt files its opens the directory and not the files
my URL looks like this “T:\FM Revit\FM Bygningsdelsbibliotek 2020.rvt”
any thoughts?
