What is the difference between “Size” and “Size on disk?”

Answer 1

Think of it like a spaghetti sauce. Let’s say you have 10 litres of sauce that you want to store in five containers. But all your containers are 3 litres, so you put 2L of sauce in 5 containers. The “size” of your sauce is still 10L, but the “size on shelf” (or on disk) is 15L.
