A script to create dummy files based on an existing (in this case, an MP4)

create_dummy_files.py

#/bin/python

# this script creates randomly sized dummy files, based on a binary type of file.
# it was used to exercise Dropbox, and see the effect of adding a removing data.
# Mostly, it was to test a third party API that was using Dropbox, and see how
# well it handled this case.
