I need a good method to find the size of a file or folder exactly as displayed in Finder. I've tried every method I could find on the internet, from using the du shell utility with NSTask to using the Carbon file manager. I need something that will work under heavy load (processing hundreds or thousands of files). The methods I've tried, some of them work but fail under load. Others just don't return a accurate file size, or they work for some files/folders and mess up on others. What's the easiest way to go about doing this?
I've had no problems using FSGetCatalogInfo. Use the physical size of both the resource and data forks. I have a suspicion that your techniques that work for some items but not others are neglecting resource forks.
