cabextract 1.4 for MorphOS, AmigaOS classic and 4.X is a program to extract Microsoft Cabinet files with ease. Cabinet (or CAB) is an archive-file format for Microsoft Windows that supports lossless data compression and embedded digital certificates used for maintaining archive integrity. Depending upon the number of files to be compressed, and the expected access patterns cabinets can be constructed in different ways. One key concept of the cabinet file is the folder. A folder is a collection of one or more files that are compressed together as a single entity. By compressing files in this way, the compression ratio is improved. The downside is that random access time suffers, since in order for any particular file in a folder to be decoded, all preceding files in the same folder must also be decoded.
