3877.0. "help with unpacking" by GVA02::SLOAN (More than a feeling...........) Tue Jun 26 1990 10:53

    Could someone pleas etake five minutes to explain the various packing
    and unpacking utilities which are currently in use. I have already
    mastered ARC and ZOO, but I am still confused with .LHW, .LZH and
    .WRP.
    Where are the utilities to unpack them, and are they available under
    VMS.
    Also, it may be a stupid question, but why are there so many.....why
    doesn't everyone standardize on ZOO or ARC?
    
    Thanks

At the current cluster speeds, it'll take more than 5 minutes... ;-)
.LZH denotes a LHARC archive. It looks and feels like ZOO and ARC, but
compresses better than anything else in this arena I've seen before.
.WRP are Warp archives, these consist of a complete disk (and as such of
any data on it, including bootblock and data sectors not mapped to files)
This is usually used for demo disks and such.
.LHW is the LHARC version of an Warp archive and as such usually smaller.

There is an (uncomplete) version of LHARC available for VMS, see recent notes
and CGOU01::AMNEW:LHARC.EXE. 
Warp and LHWarp would make little sense on anything but a target system.

Since nothing is good or even aceptable for everone. 
ARC is outdated, booth speed/compression and feature wise.
ZOO has a decent speed/compression ratio and good features like directory
structure storage.
LHARC (at least for the Amiga) has most of the features I want in an archive
utility, and is compression is superior. However you'll need patience, 
especially on a plain 68000 system.
