This page contains links to dd images used for testing by CFTT of software applications with file carving capabilities. File carving is the practice of extracting files based on content, rather than on metadata.

Currently only images for carving graphic (jpg, gif, png, etc) files and video files are available.
The dd images and layouts for graphic files can be down loaded from:
The dd files are constructed from the following graphic files:
The dd files for video files:
The original video files used to construct the dd files:
