I downloaded the *.iso file for Super Norton System Works 2003 (see somewhere on the forum here). It was about 690 MB long. Opening it by WinISO or ISOBuster gave bunch of files&folders of about 1 GB together. All of them worked. Burned the CDR by Nero, all seemed be in place, the CDR was of about 680 MB content, but some files were unreadable. Trying to create the *.ISO back - it was about 1 GB long.
How is it possible ?
