Primarily he changed the word length used by the algorithm from 12 bits to 13 bits resulting in a higher compression for typical binary files.
#PKWARE INC CODE#
It was found during the court case that Katz had used SEA's ARC source code for the majority of the application but had only made code optimizations to increase speed. Katz lost the lawsuit and was forced to pay $62,500 to SEA to cover their legal fees. The competition from Katz did not please SEA, who sued Katz for trademark infringement, as well as copyright infringement as it alleged that Katz had plagiarised sections of the code.
#PKWARE INC ARCHIVE#
This also allowed the file extractor to be incorporated into the archive file to create self-extracting archives, which could unpack themselves without requiring an external file extraction utility. Unlike SEA, which combined archive creation and archive file extraction in a single program, Katz divided these functions among two separate utilities, reducing the amount of memory needed to run them. These files worked with the archive file format used by ARC, but were faster than ARC. Later, Phil Katz developed his own shareware utilities, PKARC and PKXARC, to create archive files and extract their contents. The archive files produced by ARC had file names ending in ".ARC" and were sometimes called "arc files" as a result. These utilities were designed to gather a number of separate files into a single archive file for easier copying and distribution.ĭuring the 1980s, the company System Enhancement Associates (SEA) developed a shareware utility called ARC, based on earlier programs such as tar, that not only grouped files into a single archive file but also compressed them to save disk space, a feature of great importance on early personal computers, where space was very limited and modem transmission speeds were very slow. They include the Unix utilities ar, shar, and tar. Previous programs almost certainly existed.īy the 1970s file archiving programs were distributed as standard utilities with operating systems.
