WinZip(R) version 9.0 PRE-RELEASE BETA TEST VERSION
Copyright (C) 1991 - 2003 WinZip Computing, Inc.
All Rights Reserved
#### PRE-RELEASE BETA TEST VERSION ####
Please remember that this is a pre-release beta test version, and
that it is possible that some of the new features in this version
will not be included in the final release.
WinZip 9.0
----------
Improvements in WinZip 9.0 concentrate on its core functionality:
compression, capacity, and a new, advanced data encryption
capability. Using WinZip 9.0, you can compress more data, compress
it better, and protect your sensitive documents with far greater
security.
Details of these and other enhancements follow.
Advanced encryption
-------------------
WinZip 9.0 supports 128- and 256-bit key AES encryption, which
provide much greater cryptographic security than the traditional Zip
2.0 encryption method used in earlier versions of WinZip.
WinZip 9.0's advanced encryption (FIPS-197 certified) uses the
Rijndael cryptographic algorithm which, in 2001, was specified by
the National Institute of Standards and Technology (NIST) in Federal
Information Processing Standards (FIPS) Publication 197 as the
Advanced Encryption Standard (AES).
After a three-year competition, the AES was announced by NIST as an
approved encryption technique for use by the U.S. government,
private businesses, and individuals. When properly implemented as a
key component of an overall security protocol, the AES permits a
very high degree of cryptographic security, yet is fast and
efficient in operation.
WinZip's AES encryption is just as easy to use as traditional Zip
2.0 encryption: all you have to do is select the encryption
strength and specify your password.
Note: recipients to whom you send AES-encrypted Zip files must have
a compatible Zip file utility in order to decrypt the files. At
this time, WinZip 9.0 is required. We have, however, published the
full specification for creating WinZip-compatible AES-encrypted Zip
files, and we expect that other Zip file utility vendors will
provide support for the format.
Greater capacity
----------------
In addition to supporting the original Zip file format, WinZip 9.0
also supports the 64-bit extensions to the Zip file format. The
extended format lets you store all the data you need in Zip files of
virtually unlimited size.
The original Zip file format limited the number of member files in a
Zip file to 65,535, and the maximum size of both the Zip file itself
and any member file to 4 gigabytes. For all practical purposes, the
64-bit extended format eliminates all these restrictions. Using the
extended format, the member file size, Zip file size, and number of
member files you can add to a Zip file are limited only by your
system's resources.
WinZip remains fully compatible with the older file format and uses
the original format whenever possible. WinZip uses the 64-bit
extended format only when the limits of the original format are
exceeded.
Improved compression
--------------------
WinZip 9.0 supports the "enhanced deflate" compression method. This
compression method provides greater compression and reduces the size
of your Zip files, saving you data transmission time and valuable
disk space.
Note: versions of WinZip prior to WinZip 8.1 will not be able to
extract files compressed with this new method.
Other Changes in WinZip 9.0
---------------------------
- In addition to the new AES encryption technology, WinZip 9.0
provides a number of usability enhancements that make it easier
for you to use encryption. For example, you can now easily
encrypt the files that are already in a Zip file; previously,
files could be encrypted only while they were being added to the
Zip file.
- WinZip 9.0 makes it easier than ever for you to find the WinZip
information you need by presenting help information using the
newer Microsoft "HTML Help" facility. HTML help has a more
attractive appearance and includes many usability improvements.
- WinZip 9.0 gives you easier access to your most important file
locations in many WinZip Classic dialogs. Key dialogs such as New
Archive, Open Archive, Add, and Extract contain "places bars" when
running under Windows versions that support them. The places bar
provides quick access to your top-level locations, usually My
Computer, My Network (or Network Places), My Documents, Recent
Documents (or History), and the Desktop.
- WinZip 9.0 lets you quickly find out what is in your Zip files.
In My Computer and Windows Explorer, the tooltip that is displayed
when you position the mouse pointer over a Zip file now contains
information about the contents of your archives by listing up to
25 of the files and folders in the archive.
- When installed under Windows XP, WinZip 9.0 installs and registers
for all users. This change makes it easier to install WinZip in
business or home environments where more than one person uses a
computer.
- WinZip 9.0 contains a number of changes to improve performance and
efficiency:
- The "Use for removable media only" option for the working
folder (in the Folders tab of the Configuration dialog) is now
set by default. This results in faster Zip file creation in
most cases.
- By default, WinZip no longer automatically displays comments
when opening Zip files that contain comments.
- In Windows XP network environments, the performance of WinZip's
Windows Explorer extensions has been improved.
- Several changes have been made to improve performance when
extracting files from archives.
- WinZip 9.0's Classic interface has been improved:
- The Extract dialog has been redesigned to display more folders
in the folder tree view and to provide more space for typing
folder names.
- Placing the mouse pointer over a truncated file name (one that
won't fit in the available space) displays a tooltip showing
the complete file name.
- Because it is an action rather than a setting, the option to
"Restore all caution messages" in the Miscellaneous tab of the
Configuration dialog has been changed from a checkbox to a
pushbutton.
- The main WinZip window now contains a watermark when used under
Windows XP with an XP-style theme.
- WinZip 9.0 no longer triggers false warnings in certain security
tools that search for programs that use the "zlib" compression
library. zlib is not a WinZip component.
