From the developer:
FTK Imager provides support for VXFS, exFAT, and Ext4 file systems. Safely mount a forensic Image (AFF/DD/RAW/001/E01/S01) as a physical device or logically as a drive letter. Once mounted, the read-only media is available to any 3rd party Windows application and exposes the same file system artifacts as FTK Imager. For example, you can mount an HFS+ image, and it will show up as a volume on the examiner's machine in the explorer view.
