I have installed Acrobat on my device and then placed some acrobat files which I intend to use as help files in my program files directory of the device.

Now I want to display one of the 3 files if certain conditions exist so I thought simple enough use an if then else statement and display the correct file for the conditions.

File.Open("\program files\ax3\help1")

Does not work, so what is the correct syntax please

Also how do you close the other files that are not being displayed rather than leaving them running and using up resources
