Why isn't my ZIP file smaller than the original file was?

Question

I really need to e-mail a large file, 11.9 MB, and I tried using WINZIP but the .zip archive file is still the same size as the original file was! What am I doing wrong?

Answer 1

The file that you are trying to compress is propably compressed already, only thing what you can do is divide it in 5,5bmb parts and send two e-mails

Answer 2

This happens when you try to zip a compressed file, such as jpg. The original file is all ready compressed to the max. If you zip something like a spread sheet or a word document, it will compress a lot.
