By cheating with outside information, you can perfectly compress any
one data-set down to 1 bit. Just store the data in the program, then
store 1 bit of "is this file the data we have stored in the
program?". Granted, in modern OSes, you waste 7 extra bits since
they require you to write an entire byte at a time. :-)
And with that, you could even have an empty file and test for a file
