I've created a Setup project (in VB.Net 2008 Standard Edition) and I need to deploy some .rtf files in a specific folder for the user to edit. I've added these files to the project as content files but the Setup project installs them in Program File/MyApp along with the exe. As these rtf files need to be found easily by the user I need to specify a different folder on the hard drive. These are not mdb or xls files so are not used by the app itself. All the user needs to do is find them manually loading them into MS Word for editing. I don't need to load MS Word from the app, but I do need to deploy them so the user has access to them. How do I edit the file path so it does not bury them in Common Files or the User App Data or app folder itself? Ideally, since these are rtf files they could go in My Documents. (The app itself will work whether or not these files exist elsewhere.)
