What is DMG file

A DMG File stands for Disk Image file and it is a file format which is used to create mountable disks on the Macintosh operating system. The DMG File format contains data in the form of blocks which are often secured using encryption methods or are compressed using compression algorithms. DMG files are used for installing tools and softwares into the Mac OS operating system. The file is downloaded from the internet from the software manufacturer’s website and upon mounting the DMG file, a virtual disk is generated from where the user can either copy the application to the applications folder or run an installation script depending on the type of installation.

The newer disk image file was used in place of the original IMG or image file which was used in earlier versions of mac that are classic mac operating systems. Disk Image Files are only meant to be used in Mac based systems and not on the Windows operating systems. However, using some image softwares like Daemon tools on windows, we can mount disk images of DMG type on windows too. Some tools can also convert DMG Files to windows-recognizable image files like .ISO files.

  3. DMG files can be customized according to the manufacturer’s wish so that the installers look pleasing when people download the files for installing software.
  4. Disk images can be mounted on a computer just like a physical cd. This is a good thing as people can save a copy of the DMG file as a backup which can be used later to restore the previous state of the files.

What is ISO File

An ISO file stands for International Organization for Standardization file format which specified ISO as the standard file format for disk image files in Windows. It is a file which can be used to mount disk image files in Windows operating systems. It can be used to emulate a CD, DVD or any other disk drive in Windows virtually.

It is generally used to hold disk images of operating systems like linux which can be burned into a disk or a USB drive. It is also used to send installation files of Windows softwares through the internet but they are usually sent through a binary package with an executable or an msi installer.
