Sixty Five 7zX is freeware file archiver for Mac OS X from Sixty Five, Ltd. This program combines a number of files together in one archive file, or in a series of archive files to reduce data storage or for faster transmission. Its features include retaining OS X-specific information within archives, integration with the OS X Finder and Growl platform, and creation of self-extracting archives. As a self-extracting archive, it contains the archive file as well as the programming to extract this information. Because of the self-extracting feature, 7zX file archives do not require a second executable file or program to extract from the archive. It performs both archiving or packing, and unpacking or the reconstruction of the original files from the archive. Any user can extract 7zX files, as long as the program runs on their computer platform. This application also support gzip, tar, bzip2, UNIX compress, 7z, zip, s7z and various kinds of segmented archives.
