I should structure the write-up to first address the technical aspects: what a zipped video file is, how to extract it, considerations for file size (1.4 GB is quite large), and then move into the ethical and legal implications. Emphasize the importance of consent and legality. Make sure to warn against distributing or creating non-consensual content. Also, mention that if they have a file they're concerned about, they should consult legal experts or cybersecurity professionals.
