the math

The ISO file is 716,626 Mb
but...always is a but
right clicking over the file
Properties
There is the following information

size 699MB (733,825,024)
size on disk (733.839.366)

The ISO size is something like
716.626MB*1024=733,825,024
(no 700mb*1024, actually is bigger than)

But the cd is only 700Mb, no 716MB) How is this?

Right clicking over knoppix live-cd
Properties

the capacity is 733.825.024 699MB

then if we explore the CD and after
Select all
Properties
we see
55 files 45 folders
Size 699mb (733,370,330)
Size on disk 699 (733,427,712)

Actually in a 700MB cd are more than 733,000,000 bytes

The magic number here is 1048576 (this is from hexadecimal numbers 16 256 4096 1048576)

700*1048576=734,003,200
