WinZip Universal is a file extraction tool (or "unzipper") that can be used to unzip ZIP and RAR files, along with various other archive formats. It unzips files very quickly, compared to competing extraction tools, but it cannot unzip multi-part files or multiple files at a time. It also does not include every archive format by default - these features have to be added later. Even so, it supports most of the most common file formats by default and it works well for typical use cases.
