PKZIP® for Windows
PKZIP for Windows is a stand-alone application providing an easy-to-use interface
with powerful features and functions to accomodate any zipping task. PKZIP for Windows
includes these NEW features:
Version 5.0
- Strong Encryption. In addition to traditional PKZIP encryption,
PKZIP 5.0 increases the level of data security by introducing Strong Encryption. Strong Encryption
allows you to apply different industry standard algorithms to encrypt your data in a way that makes
it much more difficult to decipher.
- Rezipping Functionality. PKZIP allows you to quickly change the contents
of a file or files within a .ZIP archive without manually extracting and compressing the files inside
the .ZIP archive. Moreover, you can use the selected file’s associated application to make your changes.
You can use this feature with .ZIP or self-extracting .ZIP (PKSFX) archives located on your hard drive
or on your network.
- A New Streamlined Interface. Menus and toolbar buttons have been reorganized.
- Improved Wizard. The Wizard has been designed to make your archiving even easier.
- Quick Start Tutorial. We have added a Quick Start Tutorial to help you learn the basics of zipping and unzipping files.
Note: Advanced security functions are available with PKZIP Professional and
PKZIP Secure.
Version 4.5
- Compress and create .ZIP files larger than 4 Gigabytes.
The .ZIP file format originally introduced by PKWARE was limited to creating .ZIP archives
no larger than 4 gigabytes (GB). As system and storage capacities have increased, PKWARE
has extended its .ZIP file format to meet the needs of newer systems. You can now compress
files that are larger than 4 GB allowing you to create .ZIP files up to the limitations of
your computer's storage capacity.
- Compress more than 65535 files into a .ZIP file. The
original .ZIP file format limited the number of files you could compress into a .ZIP
archive to no more than 65535 files. PKWARE has extended this limit to allow you to
compress more files than ever.
- Trusted PKZIP program files. To ensure the integrity and
authenticity of the programs you receive, PKWARE has added a digital signature to the
software programs distributed with PKZIP for Windows. This ensures that the program you
install onto your computer has not been tampered with and that they are verifiably from
PKWARE.
Version 4.0
- Digital signatures can be used to sign your .ZIP archives using standard
X.509-based digital certificates. This adds an authenticity layer to your .ZIP archives
for greater security. Archives can support multiple signatures to denote acceptance of
electronic documents, such as a contract that is compressed within the archive.
- PKPatchMaker(tm), RegularSFX(tm), EasySFX(tm), AutoSFX(tm) offer many choices for
creating PKSFX® SelF-eXtracting .ZIP (.EXE) archives. Using PKWARE's patented
PKPatchMaker technology, smaller archives are created since only the differences between
old and new file sets are stored. The different PKSFX types allow different levels of user
interaction giving flexibility to the archive creator.
- Multi-paned PKZIP interface for viewing an archive's contents, favorite archive
files, and/or an Explorer-like dual-paned file manager window. The different viewing
windows can be easily moved. The application status bar allows the favorites window, the
file manager window, digital signatures and/or password encryption to be quickly enabled
or disabled. Multiple archives can be opened and viewed simultaneuously.
- New graphical interface provides easier access to all program features. Full
Drag-and-Drop functionality is provided to and from open archives or other applications.
New toolbars provide larger, more visible buttons. Option toolbars allow access to common
compress and extract options without having to open additional dialogs. Updated Add
and Extract dialogs make selecting files to compress or extract easy. Many new
configurable option settings are available to customize how PKZIP works. Options are
grouped into convenient dialogs by function. Improved graphical interface design reduces
keystrokes and helps to complete archive management tasks more quickly.
- Wizards assist novice users to extract files or to archive and compress files.
Enhanced Wizard allows creating PKSFX .ZIP archives. Wizards can now be configured to use
your PKZIP options settings.
- Enhanced compression options provide more choices for selecting compression
algorithms. The new Deflate64(tm) algorithm provides improved compression and is
backward compatible with all 2.5x versions of PKZIP. The Implode algorithm allows
creation of .ZIP archives that are compatible with applications using the PKWARE Data
Compression Library®.
- Custom Menus can be configured to launch favorite applications from within PKZIP.
- New search functions allow searching for files by filename either on your hard
drive, or in an open archive.
- Extract files from other common archives using internal support for .uue, .xxe,
.hqx, .mim (and AOL MIME), .tar, .gz, .tgz, .cab and .jar files. Configure external
programs to extract files from .rar, .bz2, .lha, .lzh and .arj archives.
- Virus scan support allows you to configure your favorite anti-virus program to
scan archives automatically when extracting files or when using the PKZIP Check-Out
feature.
- Span or Split large .ZIP archives using the spanning and splitting features.
Spanning allows large archives to span multiple removable media. Splitting allows large
archives to be split into configurable segment sizes on your local hard drive. Spanned
archives can only be created onto removable media. Split archives can be created to either
removable media or local drives for greater flexibility in transfering large files.
- Modify file information for the files within an archive without having to
re-create the archive. New menu options allow you to add, change or delete individual file
comments, file attributes, file timestamp, file names or digital signatures. You can also
add, remove or change the password for files in an archive without having to recreate the
archive.
