If you're using it to hide a bunch of CP, I don't have respect for you. But you're probably doing cool stuff like developing free software that's covered by patents or dumb laws and you don't want to get sued for IP infringement. So one idea would be to use
steganography to hide your development stuff (which should be a few dozen megabytes total at most) inside an innocuous-looking file, e.g. a large uncompressed video or audio file.
Also, like
>>27 said, you shouldn't rely on your script running before a full snapshot of your hard disk is taken. Use steganography.
