RAWImaging

Forensic (but not only) graphical frontend to work with binary images (RAW) of media in GNU/Linux. These images are universal and can be installed using both standard operating systems and popular forensic software such as Encase, Sleuthkit/Autopsy, etc. in all operating systems). The idea of the project is to implement a fast, convenient and safe making of legal copies and manipulating with images, by means of GNU/Linux, without the need for expensive hardware write lock on the media, it is necessary in the existing solutions under Windows. Also the program can be used as a last chance to rescue data from a dying media by software.
