How to open .dmg file?

Hello all,
I have one program file with .gmg extension. What is .dmg file? I want to run that program but don't know how to run it with .dmg Can anyone help?

Thank you in advance.

The DMG format replaces the .IMG file format used in Mac OS Classic and is not compatible with Mac OS 9 and earlier. DMG files are Mac-specific and are not meant to be opened on Windows; however, Daemon Tools may be able to mount some DMG images files as virtual drives; other utilities may be able to convert DMG files to a more standard format that can be recognized by Windows.

.dmg file is a (CD) disk image created for Mac OSX PC's. If the file is meant to create a CD of clipart then you will be able to unpack it for use on a Windows or Linux PC as well as a Mac. But if it contains a program that is meant to be loaded and run on a Mac only, then you cannot open it on windows.

You can open this file on MAC computer. Or TransMac for Windows can open Macintosh format disk drives, flash drives, CD-ROMs, DVDs, high density diskettes, dmg and sparseimage files.

DMG file is a mountable disk image file created in MAC operating system. You need a virtual disk to open the file on your desktop. You can use Daemon tool for that. Daemon tools can add upto more than 1 virtual disc on your system. Download the tool form down and then run it. Open the file by using Daemon Tool.
