 The Digital Forensics Virtual File System, provides read-only access
 to file-system objects from various storage media types and file
 formats. The goal of dfVFS is to provide a generic interface for
 accessing file-system objects, for which it uses several back-ends
 that provide the actual implementation of the various storage media
 types, volume systems and file systems.
