As this project contains a substantial amount of reverse engineering of the binary "queue.dat" file, it would be a good idea to look at reverse engineering techniques.
"The most commonly employed tool for reverse engineering of files and file formats is a hex editor, which typically displays files in hexadecimal and ASCII formats and assumes no knowledge of the underlying file structure." (G Conti et al., 2008)
A Hex editor will be used to decipher the contents of the queue.dat file using the information provided about where each piece of data is stored within the file. This will be identified using the table shown in the appendix about Queue.dat Structure.
