Question: When I use Meeting Pearls II, Workbench says, for example: 650 MB used. But when I calculate the size in bytes using DirOpus, I do not get the anticipated 680,525,824 bytes, but about 50 MB less. What has happened to the missing 50 MB?
Answer: A CD is written with a block size of 2048 bytes. This means that on average there are 1024 bytes waste for each file. So 50,000 files would account for a waste of about 50 MB. Well, how many files does DirOpus count for Meeting Pearls II? ;-)
The system data (directory structure etc.) uses very little space under ISO9660 and RockRidge.
