Archive Directory Viewer 2.0 (1989)
Released by 16-year old Derron Simon in 1988 and updated through early 1989. IIRC source code was released on GEnie but I've been unable to find it. It was written in C. If you somehow have the source code, please share!

DESCRIPTION
AV shows the contents of archives generated with most
popular archive/library programs. AV supports archives
created by ZOO (by Rahul Dhesi), PKPAK (by Phil Katz), ARC
(SEA), PAK (NoGate Consulting), LU (by Thom Henderson), SQ
(by a variety of authors), DWC (by Dean W. Cooper), and
PKZIP (another by Phil Katz).
FEATURES
AV has the following secondary features:
- Ability to determine archive type by the file's
extension.
- Archive type can be specified on the command line for
archives with non-default extensions.
- AV supports wildcards and command line stringing.
SYNOPSIS
AV is used as follows:
av [-alqzdp] filename[.ext] ...
"[-alqzdp]" specifies the archive type if it cannot be
determined by the archives extension. All files on the
command line are treated as the type specified. The
letters correspond to ARC/PAK/PKA, LBR, ?Q?, ZOO, DWC,
and ZIP files respectively.
"filename[.ext]" is the filename of the archive to
view. If no extension and no archive type identifier
are supplied, AV defaults to ".ARC", if no extension is
given and a type is specified, AV uses the default
extension for that archiver. Filenames may contain
wildcards and may be strung. Note: there is no default
extension for squeezed files.
OUTPUT
AV's standard output is in the form:
AV copyright notice
file1.ext
contents
file2.ext
contents
.
.
.
filen.ext
contents
The listing format is the same for DWC, ZOO, ARC, and ZIP
files.
AV uses the following terms when displaying files:
Filename - The name of the file in the archive.
Length - The length of the file before storing.
Method - The method used to store the file. Different
archive programs have different names for the same
compression methods. AV tries to use the name
used by the archive program which created each
archive.
SF - The storage factor achieved by the compression.
Size - The size of the compressed file.
Date - The date of the file before storing.
Time - The time of the file before storing.
CRC - Cyclic Redundancy Check on the file, taken before
storing with squeezed (?q?) files and after with
all others. CRC-16 is used by all the programs
except ZIP which uses CRC-32.
COMPILATION INFORMATION
AV was compiled with Microsoft C v5.1 and linked with
Microsoft LINK v3.65. The editor used when writing AV was
EC by C Source and the debugger was CodeView by Microsoft.

I am attempting to keep the number of versions of AV down to
a minimum, if you need something please get in touch with me
and I may be able to give a private version (my most recent,
which isn't necessarily the publics most recent.
FUTURE DIRECTIONS
The following are on my agenda:
- Change the user interface to something more intuitive
- Add all new archive formats
- Create a library of routines to get info from
archives that is linkable to C (for BBS and utility
writers).
