SysTools DMG Viewer is a practical and fairly simple to handle piece of software that was developed to help you open and even extract the contents of Mac OS X disk image files, enabling you to recover data, if it might have been lost or somehow damaged.

The program displays a fairly basic and underwhelming appearance, with no particularly original features about it. However, its minimalistic looks will probably be appreciated by novices, as it will require little prior knowledge in working with it properly.

The main interface of SysTools DMG Viewer is split into two main sections, on the left-side panel allowing you to ‘Explore’ the source file, or ‘Search’ through its contents, while the working window displays the items comprised by the disk image file.

For starters, you need to perform a scan operation, being able to specify the type of files you are looking for (EML, MBOX or EMLX), or you can just as easily target ‘All’ documents.

Subsequently, you can opt for a working mode: ‘File’ or ‘Folder’, and specify its location on your computer. Pressing the ‘OK’ button will cause SysTools DMG Viewer to scan your file and display a tree view of its contents in the ‘Explore’ panel.

By clicking on the recovered documents, you can view their ‘Properties’, while from the context menu, you can save an item to your Windows PC, in order to work with it unrestricted. The utility ca even work with encrypted files, as long as you have the correct password.

Alternately, if the results are too numerous to go through by hand, you can resort to the ‘Search’ component and based on a series of customizable criteria, you can find the precise file and extract it to your computer.

All in all, SysTools DMG Viewer is a useful and intuitive application that can help you regain access to files from Mac OS X computers, even if you are using a Windows system, allowing you to extract the contents of DMGs in little to no time.
