PKZIP for Windows

Experience bottom line cost reductions from conservation of bandwidth, storage space, and backup tapes.

ZIP archives are portable data containers that can be read and decompressed on many operating systems. PKWARE is the only single-source vendor of ZIP compression products across the major enterprise operating systems - interoperability is guaranteed.

PKWARE is the original developer of the ZIP compression format. Since its inception, PKWARE has made ZIP specifications available to the public as a standard for compressed data storage. Consequently, ZIP is one of the most widely used file formats in the world. PKWARE is continually reinvesting in added functionality for PKZIP brand products, making it the unquestioned leader in the industry.

PKZIP can compress files of over 9 exabytes in size.

Over 2 billion files can be included in a single ZIP archive.

Unlike other vendors who offer support only through email or online forums, PKWARE's experienced technical support staff offers live telephone support in addition to web and email support should any issues ever arise.

PKZIP supports AES or 3DES encryption using passphrases to protect valuable information. Files encrypted with PKZIP may be decrypted and extracted on major enterprise computing platforms using PKZIP or SecureZIP.

PKZIP users can decrypt and extract files encrypted with a PKI public key by SecureZIP products.

Recipients of digitally signed files can validate the signature to ensure the sender is who he or she claims to be, and verify that files have not been altered or tampered with since it was signed.

PKZIP provides a command-line interface allowing users to create scripts for automating unattended script and batch processing.

Compressing data is as easy as attaching files to email with PKZIP Outlook integration, making user training virtually unnecessary.

Good passphrases are essential to maintaining the security of your data - the longer the passphrase, the more secure it is. PKZIP allows administrators to configure the minimum length of passphrases created by users.

PKZIP can check the validity of digital certificates used to encrypt or digitally sign files against a Certificate Revocation List (CRL). When a PKZIP user receives a file that was signed or encrypted using SecureZIP, CRL checking will show a certificate that has been revoked as invalid.

PKZIP is the only ZIP utility with a Policy Manager to lock configuration options, so that compression practices can be enforced for individuals or departments - delivering considerable bottom-line savings from consistent, company-wide data compression.
