List of digital forensics tools
During the 1980s, most 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. This list includes notable examples of digital forensic tools. Memory forensics. Memory forensics tools are used to acquire or analyze a computer's volatile memory (RAM). They  are often used in incident response situations to preserve evidence in memory that would be lost when a system is shut down, and to quickly detect stealthy malware by directly examining the operating system and other running software in memory. Mobile device forensics. Mobile forensics tools tend to consist of both a hardware and software component. Mobile phones come with a diverse range of connectors, the hardware devices support a number of different cables and perform the same role as a write blocker in computer devices. Software forensics. Software forensics is the science of analyzing software source code or binary  code to determine whether intellectual property infringement or theft occurred. It is the centerpiece of lawsuits, trials, and settlements when companies are in dispute over issues involving software patents, copyrights, and trade secrets. Software forensics tools can compare code to determine correlation, a measure that can be used to guide a software forensics expert.
