Archive::Zip is a Perl module which provides an interface to ZIP archive files.

SYNOPSIS

# Create a Zip file
use Archive::Zip qw( :ERROR_CODES :CONSTANTS );
my $zip = Archive::Zip->new();

# Add a directory
my $dir_member = $zip->addDirectory( dirname/ );

# Add a file from a string with compression
my $string_member = $zip->addString( This is a test, stringMember.txt );
$string_member->desiredCompressionMethod( COMPRESSION_DEFLATED );

# Add a file from disk
my $file_member = $zip->addFile( xyz.pl, AnotherName.pl );

# Save the Zip file
unless ( $zip->writeToFileNamed(someZip.zip) == AZ_OK ) {
die write error;
}

# Read a Zip file
my $somezip = Archive::Zip->new();
unless ( $somezip->read( someZip.zip ) == AZ_OK ) {
die read error;
}

# Change the compression type for a file in the Zip
my $member = $somezip->memberNamed( stringMember.txt );
$member->desiredCompressionMethod( COMPRESSION_STORED );
unless ( $zip->writeToFileNamed( someOtherZip.zip ) == AZ_OK ) {
die write error;
}

The Archive::Zip module allows a Perl program to create, manipulate, read, and write Zip archive files.

Zip archives can be created, or you can read from existing zip files.
Once created, they can be written to files, streams, or strings. Members can be added, removed, extracted, replaced, rearranged, and enumerated. They can also be renamed or have their dates, comments, or other attributes queried or modified. Their data can be compressed or uncompressed as needed.
Members can be created from members in existing Zip files, or from existing directories, files, or strings.

This module uses the Compress::Zlib library to read and write the compressed streams inside the files.

Archiveopteryx is an Internet mail server, optimized to support heavy usage and long-term archiving.
The project stores mail in a PostgreSQL database, and provides access to it through IMAP, POP, and more.
Enhancements:
- A very serious SMTP submit bug was fixed.
- A new feature to copy outgoing mail to the sender was added.
- Support for SMTP+TLS on port 465 was added for Outlook.
- HTTP archive display improvements were made.
- A few minor bugs were fixed.

libzip library can read, create, and modify zip archives. Files can be added from data buffers, files, or compressed data copied directly from other zip archives.
Changes made without closing the archive can be reverted.
Enhancements:
- New functions were added for adding directories to an archive and to clear the internal error state.
- Zip archives larger than 2 GB and streamed zip archives are now supported.

Zipper is a tool for inspecting the contents of a compressed archive and for extracting.

I know that theres a GNUstep port of the famous OpenUp application but I must admit that for a living I have to use Windoze at work.

After a while I got quite used to Winzips UI. Although I dont like some of its features, what I really like is the content listing of an archive without actually having to unpack it. This is what Zipper currently tries to mimic.

This has also the advantage that you dont have to unpack archives from networked volumes to your local disk just to view whats in it.
