List of digital forensics tools

During the 1980s, most of digital forensic investigations consisted of "live analysis", examining digital media directly using non-specialist tools. In the 1990s several freeware and other proprietary tools (both hardware and software) were created to allow investigations to take place without modifying media. This first set of tools mainly focused on computer forensics, although in recent years similar tools have evolved for the field of mobile device forensics.
