    Can anyone explain the benefits and shortcomings of each format as a disk image? I have an interactive CD that came with a language book and that is needed for exercises. I will copy the disc as one of these formats so that I can run the program anytime on my MacBook Air. Thanks!

    As far as I know, CDR and ISO are just different names for the same thing; an uncompressed image. DMG is Mac-only but offers compression.

    For Mac-only use, DMG is almost always best.
