Coming from a VB background when we made a backup of our project files they would not work without making a few changes or using a specific backup app for such purpose. This was because some file info was hard coded for the path to the data. With B4A, what are the rules for making and using a backup? Can I just copy the project folder and open the source and make mods to my app? Or by doing it that way does it use the files from the original location? I just want to be sure that I am not actually changing the original that I am saving for a backup.
