How to open DMG files?

DMG file represents disk image format commonly found on Mac OSX. This format allows secure password protection as well as file compression and hence serves both security and file distribution functions. Its most common function is the distribution of software over the Internet. When opened, DMG files are "mounted" as a drive within the Finder.

DMG files are Mac-specific and are not intended for use in Windows; however, Windows Daemon Tools may be able to mount virtual drives from some DMG image files; other utilities may also be able to convert DMG files to a format that can be recognized by Windows.
