Open localfile using pyRevit

Revit

Hi,
Is there a way to open a localfile in pyRevit with ex. urlbutton or other?
In my case I want to open pdf or docx-files

Thanks in advanced

Python in Dynamo and pyrevit can do this in a few ways, but startfile is the most simple I’d say.

You can see some options in the answers below. Noting pyRevit has its own forums so please use those in first instance for queries not directly related to Dynamo:

import os
os.startfile(filepath)
