hello friends

I need the information on the ISO file size .
can it be much larger than the actual files size ...

I downloaded two tutorials from a website .
they are in .iso format ( 287MB & 213MB) .
instead of burning them to two CDs , I wanted
to make a single CD . so I extracted them to
two folders . Now I find that the total size of
actual files is much less than the original iso s .
(259MB & 85MB)

I used winrar 3.51 for the extraction . I doubt
if the extraction was incorrect . Testing of iso s
with the winrar showed no errors .

what do you analyze from this ? I searched the net
and found no relevant information . could you help me ...

thanks
