- #### 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.
