ARCView User's Guide
Copyright (C) 1990-94, Sergey Nazarenko, Author
ARCView is a program for those who work with archive systems to
economize disk space. You may work from the command line. The
syntax is simply
ARCView <file name>
or you may use ARCView under Norton Commander (TM) versions 2.0,
3.0 and 4.0 by pressing the <F3> key on a file name.

1. The Main Features of ARCView
ARCView:
- allows you to view a content (list of files) of archived files
with the extensions .ARC, .PAK, .ZIP, .LZH, .ICE, .CHZ, .ARJ,
.LIM, .HA and .EXE., doing this without having to use the
original archive program, and faster than the original archiver
could view it.
- allows you to view a list of files which form .SFX
(selfextracting) archives; this is an unattainable feature for
the archiver itself. ARCView recognizes over 40 different .SFX
formats.
- allows you to unpack, view contents, test, and delete files
from archives.
- allows you to work with embedded directories (subdirectories)
in archives.
- automatically determines the type of archive. If ARCView
determines it is not an archived file, it will activate the
viewer for that type of file according to the file extension
name. The viewer for these files is found in the file
ARCVIEW.EXT.
- automatically identifies files in an archive which have been
packed using a password and marks them with the symbol "*", then
requests to enter the password.
- allows you to view commentaries in archives.
- supports EGA command lines (using <Alt-F9> under NC) and other
non-standard modes (e.g. 60 lines on the screen).
- recognizes multi-volume .ARJ - archives.
- offers additional convenient features.
The table below lists the names of the executable archive files,
which ARCView uses for unpacking, viewing contents, file testing
and deletion in an archive. The search for the archive systems
occurs in the current directory and then follows the PATH setting
given in the AUTOEXEC.BAT file.

2. ARCView Installation
Installing ARCView is very simple. Run the program ARCINST.EXE.
Answer the questions the program asks you. ARCView will automa-
tically find the Norton Commander and make a backup copy of it
under the name NCMAIN.OLD. That way the old configuration is
saved if you wish to return to it by renaming the file again.
Warning:
You should not try to pack NC with programs of the type LZEXE,
DIET, PKLITE, EXEPack and similar programs. For example, NC 4.0
is distributed packed by the program DIET 1.2. (* This is the
way NC is delivered in Russia, it may not be packed when you
purchase it in Western countries). Before installing you must
first unpack it with the command
DIET -RA NCMAIN.EXE
After the correct version, size, and other internal characteri-
stics of the Norton Commander have been verified by ARCView, you
will be asked to select one of two methods to install ARCView.
The first method: ARCView replaces the viewer for Lotus1-2-3 (TM)
in the program NCMAIN.EXE with ARCView. After that when you
press <F3> while the cursor is placed on one of the files with
one of the above listed extensions, you will be able to view the
contents of the archived file. Keep in mind that ARCView can
only write six extensions under NC and ARCView cannot call .CHZ
and .EXE files, which is connected with the peculiarities of NC.
The second method: ARCView is used as a dispatcher of various
viewers contained in the module ARCVIEW.EXT analogous to the NC
file NC.EXT. When ARCView is loaded it automatically loads the
ARCVIEW.EXT file into memory. When ARCView is asked to view an
archived file by pressing <F3> with the cursor on the desired
file to be viewed, it looks for the necessary file extension to
load the correct viewer. This second method has one drawback.
It takes more memory. If you pressed <F3> while the cursor was
on the the archived file TEST.CHI, the memory map when running
ARCView might look something like this:
NC.EXE ( main kernel of NC )
NCMAIN.EXE ( NC not released from memory )
ARCVIEW.EXE ( the program ARCView itself )
CHIVIEW.EXE ( the viewer for CHI-files )
However, usually even only using a PC-AT (TM) with 80286 processor
with 1 MB of RAM under MS-DOS 5.0 (TM) taking advantage of High
Memory, all the viewers will be well placed and leave memory in
reserve. The amount of free memory is displayed in the right top
corner of the screen, for example: "═══356K═══". If the capaci-
ty is less than 120-100 KB, you should release memory, otherwise
you will not be able to run other programs from ARCView.

3.4 Function keys
<F1> Help
<Sh-F1> Information on the archive and the computer.
<F2> Selection of file list sorting by name, exten-
sion, date, time of creation, and size.
<Sh-F2> List of commentaries to the archives (if one
exists).
<F3> View of file contents. ARCView unpacks the file
in the current directory and calls the
correct viewer as determined by the file
ARCVIEW.EXE. Pressing <Esc> will delete the
unpacked file on disk. You may choose to
unpack the file on a RAM disk by using the
command SET ARCVIEW = F:\ (if you have
defined F:\ as your RAM disk). While the
file is being unpacked ARCView checks to see
if a file with the same name is present
elsewhere.
<Alt-F3> The view of the file using an alternative viewer.
<F4> Unpacks a file in the archive.
<Sh-F4> Unpacks the file to the directory specified in
the pop-up window. If the view of the full file
name is switched off, (Function key <F6>), the
unpacking of the file will be executed without
creating a directory.
<F5> Edit a file in the archive.
<F6> Hide/Display (Unhide) the full PATH to the file.
<F7> File search according to attributes including
search by file name, extension, size etc.
<Sh-F7> Repeat the last search.
<Alt-F7> Hide/Show archivers output.
<F8> Delete the current file or group of selected
files from the archive.
Warning: Be careful about deleting files. Unde-
leting deleted files is absolutely impossible.
<F9> Test of the current (or tagged) file(s). If you
see the message "CRC OK", it means the test was
successful.
<Sh-F9> Record of the current configuration is written
into the file ARCVIEW.INI.
<Alt-F9> Sets the ARJ Security Envelope to ARJ-archive.
It is a non-documented feature of ARJ that the
modification of archive files including additi-
ons, deletions, and the editing of commenta-
ries is not allowed. It is only possible to
extract files from the archive.
<F10> Exit from program.
<Sh-F10> ARCView configuration. The following window
appears on the screen:
╔═════════════════════ Setup ═════════════════════╗
║ Packer : PKZIP.EXE ║
║ Unpacker : PKUNZIP.EXE ║

║ Unpack comline : -D -O ║
║ Delete comline : -D ║
║ Test comline : -T ║
║ Add comline : -mex ║
║ Alt Viewer : wpview.exe ║
║ Temp path : E:\ ║
║ Ok ║
╚═════════════════════════════════════════════════╝
Packer - a program to delete files from an archive
Unpacker - a program to unpack files
Alt viewer - the alternate viewer loaded by pressing <Alt-F3>
Temp path - the PATH which the unpacking files will follow
when <F3> and <Alt-F3> are pressed.
If you forget to set the environment variable,
then ARCView will search for the variable TEMP,
but if it does not find it, then it uses the
value from the initialization file ARCVIEW.INI.
View comline - defines which parameters to use for extracting
one file from an archive without path by pressing <F3>
Unpack comline - defines which parameters to use for extracting a
file or files from an archive, this is used for
the extract function by pressing <F4> or <Shift-f4>.
Delete comline - defines which parameters to use for deleting a
file or files from an archive, this is used for
the delete function by pressing <F8>;
Test comline - defines which parameters to use for testing a file
or files from an archive, this is used for the test
function by pressing <F9>.
Add comline - defines which parameters to use for adding a file to
an archive, this is used for the Edit function <F5>.
4. The Setup file ARCVIEW.EXT
While viewing the contents of a file in an archive <F3>, ARC-
View uses the extension file ARCVIEW.EXT. This file may con-
tain up to 40 lines: and its structure is completely analogous
to the file structure of NC.EXT.
The format of the ARCVIEW.EXT file:
!.! File name with extension
txt: edit !\!.! !: Disk drive letter followed by a colon
^^^ └───┬────┘ !\ Path name
│ └── DOS command !! !
└── File extension ! File name without extension
The main difference between the file ARCVIEW.EXT and NC.EXT consists
in the fact that the latter must have either ! or !.! after DOS
commands and ARCView doesn't need this. If ARCView does not see the
line !.! or a similar line, it generates a command line completely
compatible to the one which NCMAIN passes on to its viewers. Besides
the file name the command line consists of about 15 parameters.
Here is an example of the way ARCVIEW.EXT might look:
arj: arcview.exe
au?: arcview.exe
al?: arcview.exe
lzh: arcview.exe
ice: arcview.exe
zip: arcview.exe
arc: arcview.exe
msg: msgview.exe !\!.!
chz: arcview.exe
exe: hiew.exe !\!.!
com: hiew.exe !\!.!
ovl: hiew.exe !\!.!
chi: chiview.exe !\!.!
pcx: pcxview.exe
fli: aaplay.exe !\!.!
db: paraview.exe
123: 123view.exe
dbf: dbview.exe
gif: command.com /c av.bat
???: wpview.exe
