The .ISZ format was created by EZB systems and is based on the common disk image format .ISO but with added compression to reduce file sizes. If a .ISZ compressed file is too large for the destination media (I.E a CD) it can be split in to multiple files. The .ISZ format can also support password protection and AES256 (256 bit Advanced Encryption Standard) encryption.
