PKZIP Command Line is the latest version of the popular data compression program from PKWARE, Inc. PKZIP is a powerful utility that provides many functions for data compression, file archival, management, and distribution. PKZIP has led the way in industry standard .ZIP format compression since 1989, when PKWARE introduced the .ZIP file format. ------------ INSTALLATION ------------ PKZIP Command Line is installed using the Microsoft Windows Installer. This installation process makes installing and configuring PKZIP Command Line easy and avoids common conflicts that can arise when installing new software. If you have purchased a REGISTERED copy of this software, it is distributed either on CD-ROM or as an electronic delivery file available for downloading from the Internet. If you have a SHAREWARE copy of this software, it will be distributed using a PKSFX(R) self-extracting file. Installing from CD-ROM: If you are installing from CD-ROM, simply insert the CD into your drive. The Autorun feature will automatically start the setup program. If the Autorun feature is not enabled on your system, you can run SETUP.EXE directly from the CD. After the setup program has started, follow the instructions provided on-screen to complete the installation. Installing from a PKSFX file: If you are installing a version of the software downloaded from the Internet (i.e. either a REGISTERED version purchased online, or a SHAREWARE copy downloaded from an Internet site such as www.pkware.com) you will receive a PKSFX self-extracting file. The Windows Installer is packaged inside the PKSFX file. Run the PKSFX file to start the installation. It will extract the files needed to install the software and it will automatically start the setup program. Follow the instructions provided by the setup program to complete the installation. When you run the PKSFX file, the files it contains are extracted to an intermediate folder and the installation continues from this location. Once PKZIP Command Line is installed and working properly on your system, you may delete this intermediate folder to free up disk space. If you delete this intermediate folder but later want to reinstall the product, you will need to re-run the PKSFX file. We encourage you to make a backup of your PKSFX file, or of the contents of the intermediate folder to ensure you will be able to reinstall this product if you ever need to in the future. ------------------- SYSTEM REQUIREMENTS ------------------- PKZIP Command Line is intended for use on Microsoft Windows 95, Windows 98, Windows Me, Windows NT 4.0, and Windows 2000 systems.
