File extension dmg information
Description: The disk image file that is created under the operating system of Apple Macintosh computers uses the file extension .dmg. It has replaced the previously utilized IMG format type. The .dmg file extension is used for the mapping of folder trees including its contents. This allows for the mounting of files (virtual) on a computer system simulating a real drive. The mounting process of the file extension .dmg is done regardless whether the contained data is an existing image device or not, and it is commonly utilized for the distribution of software applications that are deployed for the Apple computer.The file extension .dmg is created under the Mac OS X and later versions. It displays the virtual drive on the user's desktop, which is typically identified with Apple system-based installation files that are downloaded from various Internet sites. The file extension .dmg's predecessor format (IMG) was identified with the Mac OS Classic platform and is not compatible with older operating system environments. Apple provides disk utility tools that are bundled with the Mac OS X distribution installer, aside from other third party software applications that can competently handle the .dmg file extension. The usage of third party software applications are primarily for the purpose of converting the .dmg file extension to a format that can function properly under MS Windows-based machines. The file extension .dmg is comparable to the ISO or BIN format type that exists under the Microsoft Windows environment.
