Documents in the modern Office suite use XML files stored in zip files; what you see as a ".pptx" or ".docx" file is actually just a zip file containing XML files.

Create a file called "assignment3-report.txt" in your home directory; in that file, respond to the following:

  1. Run your bin/file-identification.sh script over both Data/00 and Data/01, and include all of the results.
  2. Looking at the Powerpoint file in Data/00, what data can you extract about the possible origins of this document? How did you extract this data?
  3. Looking at the Excel file in Data/00, what data can you extract about the possible origins of this document? How did you extract this data?
  4. Looking at the Word document in Data/00, what data can you extract about the possible origins of this document? How did you extract this data?
  5. Run the program "exif" over each of the files Data/01, and include all of the results.

Please submit your "assignment3-report.txt" on Blackboard, and please also leave it on 45.56.74.139.
