    Default Re: How does winzip work?

    Winzip uses compression.
    Simply put (courtesy of the web)

    Compression uses what is known as an algorithm (any set of instructions to be followed in order) to take a data file as input and make sure the output is a much smaller file. As an example, take a string of characters -

    cheese and ham and more cheese

    How else could this string of characters be represented? Well, we could make up a code. Notice the words "and" and "cheese" appear twice in the string, we could encode (compress) the string as follows:


    to get:

    b c ham c more b

    If this is applied to a whole file only concentrating on frequently used code or text, the file could be made considerably smaller. This is an example of a fixed length code.
