DMG Master is a document based app to create standard DMG Archive with just one click.


DMG Master peculiarity is to save archive creation settings in documents.
Thanks to that, you can do a lot more then with just a 'utility' apps.

The 'document based' approach used by DMG Master lets the user save a lot of time in the use of the software if compared with the classic 'utility' approach.

The disk image is created on the fly with the updated content as specified inside the document.
