DMG2IMG

DMG files are specific to the MAC OS X operating system and you need a specialized program to open them in Windows. But this compatibility problem can be solved using a converter application. A good example is DMG2IMG.
This is a small and lightweight application that allows you to convert DMG files into the standard disk image format, IMG, which is compatible with more programs on Windows. The tool allows you to convert zlib and bzip2 compressed DMG images to standard image disk files. It is useful, as it can process even larger files.
The main drawback of the application is that it opens with the command console and does not offer a standard user-friendly interface. Thus, for those who are not used to working with command lines, it might pose some problems regarding the syntax.
On the other hand, if you are familiar with the commands in the console, using this application can seem really easy. For the conversion to succeed, you have to follow the exact instructions. There are two usage command lines for making the conversion and several options to configure.
Silent mode, verbose and extremely verbose, debug are some of the available variables that you can change according to your preferences. In addition to this, you can choose the partition list to be extracted or choose to extract only a specific partition.
After you configure all the mentioned parameters and write the correct command, the program starts the conversion and you can view the progress indicator.
Although it might pose some problems to inexperienced users, DMG2IMG is a handy tool capable of solving file compatibility issues easily and fast.
