I have a app built in Creator where the use can attach a document / file  (alway a pdf) , The default behaviour when the user clicks the link is for the file to download.

I would like to file away to force the file to be viewed either in my chrome browser or in the default app,,Adobe acrobat

I have thought of copying the link and modifying it in some way and drop it into a url field with the hope to force the file to open in the default program Adobe Acrobat.

Any ideas ?
