WinRK is a new high performance file archiver. Built from the ground up for better compression and security, it provides the best platform for managing and creating file archives. WinRK supports all the most common archive formats in use today, ZIP, GZIP, BZIP2, TAR, RAR and ISO. WinRK's ZIP support is fully compatible with both the Zip64 standard and the new WinZIP AES encryption standard. This means that ZIP files created with WinRK can take advantage of file and archive sizes of over 4GB, along with strong encryption capabilities. The ZIP deflate and deflate64 algorithms have been improved as well, providing 10-20% smaller archives in most cases, without loosing any compatibility!
