WinRK
WinRK is a commercial file archiver program for Microsoft Windows. It is produced by the “M Software” company, which is located in New Zealand and which consists of a single person, Malcolm Taylor.
WinRK supports its own proprietary RK archive format and additionally the popular ZIP, gzip, bzip2, tar, RAR, and ISO file formats. The program's ZIP support is compatible with the AES encryption scheme used by the latest WinZIP versions, and with the newer Zip64 standard. This support allows for both big archive file sizes (over 4 GiB) and strong file encryption. WinRK comes with an extensive GUI.
Later versions of WinRK provide a DLL-based plugin API, allowing developers to extend WinRK to support alternate archive formats and compression schemes.
The algorithms used by WinRK with its own RK archive format are ROLZ (first implemented in WinRK, based on LZ77), PPM and PWCM (a descendant of Matt Mahoney's PAQ algorithms).
Reviews done by maximumcompression.com show WinRK delivers the highest compression-ratios of programs in its class. It lacks a freeware extraction utility (RAR for example provides such for many systems), though it is capable of producing self-extracting archives (Windows only, might cause problems on older versions).
