WINZAP is a free file compression tool that allows the user to "zip" files, as with other completing programs such as the similarly-named WinZip. WINZAP differs in that it focuses on compressing files, allowing the user to move large numbers of files and folders into one archive. It's very easy to use, and it creates archive files that most common apps can open, but it isn't very flexible: it offers few options or bells and whistles, and doesn't offer many formats to compress files to.
