An archive is a file that contains (possibly) multiple compressed files. It will also usually contain additional information about the file, such as file length, date, permissions, compression type, and so on. One of the most popular formats for file archives is the Zip format, originally developed by PKWare, and now supported by many other free and commercial programs.
Library of technical articles along with code samples written and supported by Andrew Polar. Contains articles and source codes on Huffman and range coder. Readers may found another topics of interest not related to data compression, e.g. a simple Web server in sources.

makeself is a small shell script that generates a self-extractable archive from a directory. The resulting file appears as a shell script (many of those have a .run suffix), and can be launched as is. The archive will then uncompress itself to a temporary directory and an optional arbitrary command will be executed (for example an installation script). This is pretty similar to archives generated with WinZip Self-Extractor in the Windows world. Makeself archives also include checksums for integrity self-validation (CRC and/or MD5 checksums).

It has been designed to utilize a single executable for all functionality and has proven to be more effective than most archival utilities on the market today. Although SAR does not have a lot of the commands other utilities have, it more than makes up for it in compression and ease of use. Future releases of SAR will continually include more functionality.

Zoo is used to create and maintain collections of files in compressed form. It uses a Lempel-Ziv compression algorithm that gives space savings in the range of 20% to 80% depending on the type of file data. Zoo can store and selectively extract multiple generations of the same file. Data can be recovered from damaged archives by skipping the damaged portion and locating undamaged data with the help of fiz(1).

PAK is a utility to create and maintain file archives in compressed form. There are several advantages to compressing files. On a hard disk, most files are accessed infrequently. Reducing the size of these files allows more of them to remain on the hard disk, where they are more accessible than on a floppy in a file cabinet, and
frees disk space for other use.

Together, PKPAK and PKUNPAK handle all of your file compression needs. PKPAK is the program that compresses files. This shrinking process is often referred to as archiving or ARCing and it results in the creation of an ARCHIVE file. Terms you will see during the compressing process are Stored, Packed, Squeezed, Crunched and Squashed. PKPAK also handles all ARCHIVE file maintenance including adding and
deleting files, as well as reporting on technical information from
within the archive.

SQPC is derived from the SQ File Squeezer written by Richard Greenlaw. SQPC was written using assembly language to achieve a smaller program file and to improve performance. It uses the same Huffman encoding algorithm for creating a squeezed file from any input file. Additionally, SQPC allows the use of path names and wildcards, and it incorporates the file date/time stamp feature employed in the newer version of SQ known as NSQ.
