.ISO file size information

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

i also had a similar problem..downloaded a iso from net which was ~700mb..extracted to 4.2 GB .. :o

even if i added or modified anything using a iso manager the size would come near to 4 gb…:frowning:

well i have never heard about bloated iso’s plz tell me seshu wat have u downloaded(maybe thru PM),
but super_saiyan, the iso’s u have encountered are optimized iso’s, it must be an all in one iso which is having a lots of versions of same program like allversions of windows xp

Try specialized software, like powerISO, magicISO or so.

Yes its ri8!

It will be larger in size if its extracted…using ny of d iso edits…

some files will be used by more than 1 reference in the applications..
N dose will be written only once, n rest will be given reference(aka sfotlinks)..
wen extratced.. it will be more in number of files…so the size also…

other than that… in the process of making an ISO u can do compression also… even it cld be bcoz of this…

No worries… with that…
