Is there a simple way to determine the amount of hard drive space a feature class takes up? I feel like I'm missing something simple, but I don't recall a method that does so. You would think that right-clicking a dataset in ArcCatalog would do it for you. The best I've ever been able to do was get the size of the entire gdb by looking in Windows Explorer. If there isn't a way to do this in the ArcCatalog UI, I'd still be interested in a method to do so in code.
