The zip format typically allows us to compress most file types in an effective manner thus reducing the amount of space needed for storing those files. While file formats such as text or word documents tend compress significantly some file formats, especially multimedia files do not seem to compress by any notable degree.
What makes multimedia files difficult to compress
Most multimedia files like MP3, AVI or JPG tend to already exist in a significantly compressed state. The fact that they are already compressed does not allow them to be further compressed by a great value when you zip them. However not all multimedia files seem to display this behavior and formats such as BMP can be compressed by a large extent.
