WinZip is the original and most popular of all Windows Zip file utilities. Combining power and flexibility with ease of use, WinZip appeals to the entire spectrum of data-compression users. First-time users are comfortable with the intuitive WinZip Wizard, while power users appreciate WinZip's seamless Windows Explorer interface and choose the award-winning WinZip Classic interface for their most sophisticated compression needs. In addition to basic zipping and unzipping, features include tight integration with Windows Explorer, support for most Internet file formats, advanced AES encryption, and much more.

Formerly EasyZip 2000, this archiving tool features support for ZIP, CAB, LHA (LZH), TAR (+TAR.GZ, +TAR.BZ2), and BH (BlakHole) formats. The program features complete integration with Windows, including new Office 2002-style toolbars, forms, and buttons. It also allows you to drag and drop to and from Windows Explorer, and extract archives and ZIP files directly from Windows Explorer. You can rename files in an archive, create archives spanning multiple disks, view and write comments, run a virus check from within an archive, and test and password-protect archives. There is a tool for extracting multiple archives and an internal viewer for GIF files. Version 8.0 features unlimited ZIP size support; support for Deflate64; RAR v3 support; and much more.

WinRAR is a 32-bit Windows version of RAR Archiver, an archiver and archive manager. RAR files can usually compress content 8 percent to 15 percent more than ZIP files. WinRAR's main features include strong general and multimedia compression, the ability to process non-RAR archive formats, ZIP compression and decompression, long filename support, programmable self-extracting archives (SFX), damaged archive repair, authenticity verification, embedded file comments, and encryption. Unicode is supported in archive filenames, allowing non-English filenames to be handled painlessly. You can manipulate the parameters of many archives at once and view a volume sequence as a single archive. WinRAR is able to convert other archive formats to RAR. It supports the Find command, allowing search for specified text and files in archives. The latest WinRAR version can rename files inside of RAR archives and preserves file time using the high precision NTFS time format.
