ARC File Archive Utility V 6.00
ARC is used to create and maintain file archives. An archive is a group of
files collected together into one file in such a way that the individual
files may be recovered intact. ARC automatically compresses the files being
archived so that the resulting archive takes up a minimum amount of space.
When ARC is used to add a file to an archive it analyzes the file to determine
which of three storage methods will result in the greatest savings. These
three methods are:
1) No compression; the file is stored as is.
2) Repeated-character compression; repeated sequences of the same byte value
are collapsed into a three-byte code sequence.
3) Dynamic Lempel-Ziv compression; the file is stored as a series of
variable size bit codes which represent character strings, and which are
created "on the fly".
*** PAK ***
PAK is intended as a replacement for ARC by System Enhancement
Associates and PKARC by Philip Katz. While PAK is faster than ARC,
speed is not the emphasis, and PAK does not attempt to compete with
PKARC in this respect. However, PAK produces archive files that are
consistently 50% to 90% of the size produced by either ARC or PKARC,
and supports files created by either program. Also, the full screen
version is much easier to use than ARC or PKARC.
