    I ask the following in order that I get a better understanding of disk images.

    Unlike (I believe) creating disk images with any other utility, OSX's disk utility (hdiutil) will allow you to create a .dmg file in which the contents are purely data in the form of folders as opposed to attached mass storage such as disks. Creating a .dmg to distribute a disk is understandable, but why do the same for a folder which can be easily compressed and distributed and interpreted by universally installed software?

    User convenience, I guess. With disk images you mount them, do whatever you need and eject them. Easy and does not clutter up the disk with inflated files from compressed archives.

    That and disk images allow for EULAs, graphics and probably more.
