Here's how to save them to the right location when you add new recipe boxes to your PC:
First, make sure that BigOven or BigOven InspiredCooking Deluxe is installed, but not currently running.
Look for your "My BigOven Recipes" folder. By default, it is created in your "Shared Documents" folder; the full path to this location is usually C:/DOCUMENTS AND SETTINGS/All Users/Documents/My BigOven Recipes for Windows XP. In Vista, it is C:/Users/Public/Documents/My BigOven Recipes
Take a moment to inspect the "RBox" subfolder of your "My BigOven Recipes" folder that you found in the step above. Note that for every Recipe Box, it contains a folder with the name of the recipe box, then the recipe box file itself with a CRB extension, and a folder called "Pictures". This is how all recipe boxes must be saved to your PC for BigOven to be able to work with them. They are all at the same "level", or depth, in the directory.
