On average, you will expand files, not compress them.

Also, the odds of getting finding even a single encrypted file of that length which can be compressed are lower than the odds of winning the lottery three times in a row. Trust me, you didn't just happen to stumble across a working example. You screwed up the test.

There are no real patterns in encrypted data. Only tiny exponentially rare streaks. This means that compressing is still useless, as originally claimed. You're arguing against something that wasn't said.
