Upon mounting the file, the generation of a virtual disk takes place from where you can copy the program to applications or simply run the installation script; choosing between these two options depends on the installation type. A DMG file comprises of a raw block of data that is encrypted in various encryption methods and compressed through multiple compression algorithms as well. If you wish to protect a DMG file, you can always apply a password.

DMG files are usable only on Mac computers and hence not compatible with Windows operating systems. If you would like disk image files in your Windows computer, you must use ISO files, which use the International Organization for Standardization file format. ISO files are perfect at mounting disk image files in any Windows operating system, especially the most recent, Windows 8 and 10.

Some people use them to emulate DVDs, CD or other disk drives virtually. An ISO file also holds the disk images of operating systems such as Linux that you can copy in the USB drive or burn into a disk. It can further send Windows software installation files online. However, a binary package with the MSI installer is used to send the files.

Unlike DMG files, ISO files are compatible with Mac operating systems. On the other hand, the ISO format lacks features like compression algorithms and encryption methods. Since ISO files are compatible with Mac and Windows, it is advisable to turn DMG into ISO.
