The explanation of the functions and nature of operating system software and applications introduced the processes of file creation, file transfer, and the storage of electronic information. The chapter introduced and explained the nature of filesystems and outlined some typical files that contain evidence of evidentiary value and where they may be located on devices. A summary of password security and encryption has shown that digital devices are becoming more advanced and are using encryption as an effective security feature. This now poses some significant problems to practitioners attempting to look for concealed evidence.
