Q20: How do you unpack a .ARK or .ARC file?

A: (Gier Tjoerhom, Don Kirkpatrick)

Archive files are a collection of related files packed together so

they stay together. They have somewhat been replaced by librarys,

but are still encountered often. The C or K at the end only

differentiate the original packing program, they are otherwise

identical. Some archives are self extracting, just rename them

with a .com ending and execute them. Others must be unpacked with

a program, unarc16.ark containing one of the most popular (in a

self extracting archive). This archive can be found at:

oak.oakland.edu: /pub2/cpm/arc-lbr/unarc16.ark

Q21: How do you unpack a .lbr file?

A: (William P. Maloney, Peter A. Schuman)

A .lbr is a single file that contains a number of compressed files

inside. The files must be extracted from the .lbr before the can be

used.

One very good library extract program is called lbrext.com. It's

simple to use and uncrunches the files at the same time. EXAMPLE:

A>lbrext b:myfile.lbr c:*.* uo

This takes the lbrext.com file on 'A' to extract all the files in

myfile.lbr on 'B' and put them on 'C' uncrunched. A simple 'lbrext'

first will show you how to use the .com file.

Other popular library maintenance programs are LUE, DELBR, and NULU,

the latter being one of the best CP/M programs for handling LBRs.

However, don't use NULU to extract and unsqueeze simultaneously. It

occasionally screws up doing this, and it can trash an entire disk

when it does so.

LT31 is also able to unpack libraries and also supports all

current compression standards (including LZH 2.0!). It is a very

useful utility and can replace several single programs.

Q22: What are all these .xQx, .xYx, and .xZx file types?

A: (Don Kirkpatrick)

These are compressed files, a.k.a. squeezed or crunched files. They

must be uncompressed before they can be used. They differ in the

compression algorithm; .?Q? was the first generation and .?Y? the

newest. There are many fine programs that uncompress files, but

most handle only one or two compression types (e.g. SQ111.ARC and

CRUNCH24.LBR). One program that will uncompress all three types can

be found in CRLZH20.LBR.

Q23: Are any of these .ARK, .LBR, or CRUNCH utilities on MSDOS?

A: (Geir Tjoerhom, Mike Finn)

Yes, MSDOS versions do exist and can be located as follows:

oak.oakland.edu:/pub/msdos/arcutil/lue220.zip (.LBR)

ftp.switch.ch:/mirror/simtel/msdos/archiver/arce41a.zip (.ARK)

nic.funet.fi:/pub/msdos/simtel/compress/alusq.com (.xQx)

nic.funet.fi:/pub/msdos/simtel/compress/uncr233.zip (.xZx)

ftp.cts.com/pub/donm/cfx.zip (.LBR, .xQx, .xYx, .xZx)

Also check out the files in oak.oakland.edu: /pub/unix-c/cpm.

CFX is the acronym for Cp/m File eXchange by Carson Wilson. As its

name suggests, CFX is a tool intended to allow quick access to CP/M

files. While CFX will operate on standard ASCII files, its main

strength is its ability to access files stored with the special

archiving and compression methods native to the CP/M operating

system. Specifically, CFX can handle files compressed with Roger

Warren's LZH utilities (.xYx), Steve Greenberg's CRUNCH utilities

(.xZx), "squeezed" files (.xQx), and archives built using Gary

Novosielski's Library definition (.LBR).

Da du ein Z-Sytem hast solltest du den VLU - Video Library Editor nutzen können.

Moin Fritz!

Danke für die Pointer.

Ich habe so lange nix mehr mit dem ZSystem gemacht, da fehlt mir etwas die Übersicht.

NB Ich habe eine CP/M CDROM von Walnut Creek (Nov '94). Falls Du Interesse hast, kann ich Dir ein Image irgendwo ablegen.

Sind nur schlappe 635M

Danke für das Angebot , ich nehme aber doch lieber die hier  .

Und hier ist noch ein wenig Dokumentation
