LOL, easy, just drag them into each other and it creates folder automatically.
If you guys want a top appl that identifies the calorie of everything you can think of, from eggs, to a protein shake, to a bowl of oats, to a piece of chicken breast etc. etc., then I strongly recommend you download MyFitnessPal.
Probably the only application I haven't been sick of using after a few days.
I use this one as well. The coolest thing is if you have an iphone 4, you can use it to scan the barcodes of the products you eat, and it automatically adds all the nutritional info for the product.
So, using myfitnesspal, I scanned the barcode of my oats box, add the serving size and it adds all the details of the oats to my daily consumption.
