The zip compression format does not always result in the greatest compression or file size. There are other compression formats that each have advantages and disadvantages. Some do very little compression, but perform the compression quickly, while others have very high compression but perform the compression slowly. Others tend to be good at both. The type of files being compressed will also make a big difference in the compression ratio, since some files formats, such as music and video, are already compressed by nature. Each compression type uses a different algorithm for compression as well.
