[PDF] open an external directory?

[Stan Drew with Golden Images]

Hi, This should be a simple function for me to figure out but I am having a difficult time with it. I am creating a PDF interface menu that allows a user to click a button or link and open certain PDF files that I have created. The issue that I am having a problem with is that I need to create a button or link that will open in a new window a particular directory, which contains a number of different files. Thus allowing the user to see that particular directory contents and make their choices. What would I need to do in order to create this? Seems like it should be an easy thing to figure out. Any help would be appreciated. I am using both Acrobat 4 and 5.   Stan Drew
