Directory lister & utility for ARC ARJ LZH LZS PAK ZIP ZOO. Displays sorted
member names by default. Converts self-extracting (SFX) archives to normal
archives. Resets archive dates/times to match newest member. Strips extra
bytes from ends of ARJ/LZH/ZIP files. Strips/attaches ZIP file comments.
Sorts ZIP/LZH files on disk. New: Fixes bug when displaying compressed

===========
RView and this documentation are offered as is. The user bears the entire
risk of this software not performing as expected.
Purpose:
========
To provide a single, stand-alone program capable of listing directories of
several archive formats. Filename extensions are ignored in determining
archive types.
This utility also contains various features not conveniently provided
elsewhere at the time of their inclusion.
RView is a free program.

The type of archive is displayed before listing each archive. For
self-extracting archives, the letters "SFX" follow the name of the base
archive type. The program further distinguishes between small- and
large-model LZH SFX archives and shows which ZIP SFX's are of the "Mini"
type.
For ZIP 2.0-type archives, the three different variations for "deflating"
are reported as "Deflate", "DeflateX" and "DeflateF" for Normal, maXimal and
Fast compression, respectively.
Compression factors ("CF") used by RView may be expressed as follows:
100 - ( CompressedSize / OriginalSize * 100 )
Thus, the larger the number, the more disk space saved by compressing.
The date and time indicated on the "totals" line represent the date and time
of the most recently created or modified member of each archive. These are
the values used by /R in resetting the archive date and time.
RView displays the total number of bytes required to contain the listed
members if extracted to a selected drive. If no drive is selected, the
drive containing the archive being listed is used. In making this
computation, RView takes actual disk cluster sizes into account.
Syntax:
=======
Usage: RV [switches] archive_name [d:] [member_name...]
Switches (optional) may appear in almost any position on the command line.
'-' may be substituted for '/' wherever DOS allows.
In the above syntax, "archive_name" may optionally include a drive and/or
path designation. An archive name specified without an extension will
result in a search for all extensions. Thus typing "RV filename" is
equivalent to "RV filename.*". Also, "RV *" is equivalent to "RV *.*".
An optional drive may be included immediately after the archive name to
check for extraction sizes to the indicated drive.
Example: RV backup.lzh a:
Result: Causes RView to compute extraction sizes for drive A:.
File specifications following the archive name will limit the listing to
only those members matching any of these specifications.
Example: RV source.zip *.h *.c
Result: Causes RView to list only C header and source files
contained within SOURCE.ZIP.
Switches:
=========
/W List members in Wide display format. Displays up to five names
per line.
/B Brief filenames, without path. Use this switch to suppress the
display of full pathnames, i.e. only the filename.ext parts of
full pathnames will be shown.
/P Pause display after each screenful. After pausing, pressing
almost any key causes another screenful to be displayed.
/N List members in Natural order. Member names are displayed in the
order actually stored on disk.
/R Reset date and time of archive. The date and time used will be
those of the most recently created or modified member of each
archive.
/D Sort LZH and ZIP files on Disk. The local headers (and central
directory headers for ZIP files) of unsorted archives are written
back to disk in sorted order. Nothing is done for already-sorted
archives. Sorting to disk is available so that LZH and ZIP files
will be displayed in sorted order by listers that don't do
in-memory sorts. Also, disk-sorting is useful for LZH files when
telops ('!' files) are used.
/L ReLax checking. If RView's default mode isn't able to list an
archive, this option may allow it to do so. Use this option with
care, especially in conjunction with other options which actually
modify archives.
/U[path] Un-SFX self-extracting archive. Converts self-extracting (SFX)
archives to normal archives. A new file will be created with the
same name as the SFX file but with the appropriate extension
(".ARC", ".LZH", etc.). The normal archive is written to the
current directory by default. "/U" followed immediately by a
valid path (no intervening spaces) allows writing to the
specified target drive/directory.
/C[file] Strip/attach ZIP file Comment. Strips ZIP file comments from ZIP
files. If a valid filename immediately follows "/C" (no
intervening spaces), then comments contained in that file will be
attached to any ZIP files matching "archive_name".
/X Strip eXtra bytes from end of archive. XMODEM-type file transfer
protocols often pad transferred files with added bytes. This
will truncate ARJ, LZH and ZIP archives to reflect their "true"
sizes.
/A Strip All - same as /U /C /X.
/I Ignore previous switches. This option was added by user request
to provide some means of overriding the defaults specified in
RV.CFG. Using this switch causes all previous switches, both in
RV.CFG and to the left on the command line to be "forgotten",
thus temporarily resetting RV back to "factory defaults".
Keyboard commands:
==================
By user request, beginning with Version 2.34, the single-key,
program-pausing feature has been added back. To use this, while RView is
displaying an archive, pressing <Esc> will terminate execution. Almost any
other key will pause the program. After pausing, pressing <Esc> will
terminate execution. Again, almost any other key will resume execution.
Configuration:
==============
A free-form configuration file containing user-selected default switches may
be created or edited with any editor or word processor which can write pure
ASCII text files. This file should be named "RV.CFG". Only the first 1024
characters of RV.CFG are significant. This file is "free-form" in the sense
that switches may be freely interspersed with comments. In creating or
modifying this file, avoid the use of the '/' and '-' characters in
comments, as these may be interpreted as (sometimes invalid) switches.
RView will search for RV.CFG first in the current directory. If it is not
found there, then each directory in the PATH is searched. Incompatible
switches used on the command line will override switches included in RV.CFG.
Switches are evaluated from left to right on the command line.
A sample RV.CFG file is included in the distribution archive for RView.
Please note that this is only a *sample* .CFG file. After extracting the
contents of the distribution archive, RV.CFG may be safely deleted if
RView's defaults are satisfactory.
