Free pkzip software for windows

PeaZip 2.7 beta is truly a perfect program for 32 and 64 bit Windows and Linux. It is available either as installable and portable application (not needing installation).

PeaZip can extract most of archive formats both from Windows and Unix worlds: currently 87 file extensions are supported ranging from mainstream 7Z, RAR, TAR and ZIP to experimental ones like PAQ/LPAQ family, currently the most powerful compressor available.

For archive creation, PeaZip suppors a wide range of compression and encryption standard, from fastes to most powerful ones, and allows to export job definition as scripts to bridge the gap between GUI and console applications, and let the user pick the best of the two worlds.

You can use PeaZip on all Windows version and on Linux (PeaZip is a desktop neutral application) with the same features and look and feel; moreover, for both platforms, PeaZip is also available as standalone, portable application not needing installation.

• 7Z's AES256 encryption
• ZIP WinZip's AE encryption based on AES256 (and ZipCrypto for legacy compatibility); can decrypt PKZip's AES encryption
• FreeARC's ARC: AES256, Blowfish, Twofish256 and Serpent256 - this format is also capable to generate recovery records to protect data against corruption
• PEA: AES256 EAX authenticated encryption

2. PeaZip allows to apply powerful multiple search filters to archive's content; create and extract multiple archives at once; create self-extracting archives; export job definition as command line; save archive's layouts; bookmark archives and folders; scan and open with custom applications compressed and uncompressed files etc...
3. Other features: strong encryption, robust file copy, split/join files (file span), secure data deletion, compare, checksum and hash files, system benchmark, generate random passwords and keyfiles.

Enhancements:

• GUI
• • (PeaLauncher) added option to open output directory after operation
  • File browser
  • • it is now possible to force refresh inside archives
    • the password / keyfile can now be set once, for being used in file browser, archive creation (setting password triggers use of encryption) and archive extraction, like in WinRar; the locker icon reports if the password is set

    • clipboard is now displayed in a panel at the bottom of file browser, like history and bookmarks
  • Archive creation interface: new task oriented GUI for compression, adding / dropping files and folders to archive uses the archive creation interface (like in WinRar, where adding to archive raises the archive creation dialog)
  • • can optionally archive each input item to separate archives
    • can chose output path with a powerful navigator (like in former "extract to" popup menu): system's paths, bookmarked folders, recent folders
    • supports use of the advanced inclusion and exclusion filters (7z and FreeArc backend)
  • Archive extraction interface: new task oriented GUI for extraction
  • • the advanced inclusion and exclusion filters (7z and FreeArc backend) are supported also for multiple archives at once
• BACKEND
• • updated FreeArc to 0.51
  • • can now create FreeArc's self extracting archives (sfx creation not jet working on Linux packages)
  • updated 7z to 9.06 (Windows)
  • • open mslz, flv, swf, gnm
  • added backend for ZPAQ (Windows), currently supports only extraction to original absolute path
• 95 file extensions supported

Simple utility that can ZIP files using a simple script file that can contain various settings and filelists. Who today does not often use some ZIP compressor utility like WINZIP, PKZIP and others? They are great but they usage is oriented to much manual work - you need to select files, make clicks etc. etc. etc. ...
But if you often need to ZIP the same or simmilar set of files, instead to make your work easier those ZIP utilities can make it harder. For example - how many times you wanted to click only once and leave ZIPper to do the job ? Well, ScriptZIP is made for all "lazy" people who want more comfortable work.
ScriptZIP is a simple, small and easy-to-use tool that can ZIP files using a simple script file that can contain various settings and filelists. It is especially usefull if you often ZIP the same group of files (for example, for making backups) because you can write a script with desired options and settings for each set of files. When you make a script, compressing is trivial - all you need is to doubleclick on script and - voila!
Main features:
- Backup feature - keep up to 7 backups of ZIP archives (Round-Robin backup method)
- It is possible to define include and exclude file list where you can define what files you want in ZIP and what dont
- Particular set of options can be set for each file list (how to add files, define attributes, compression level etc.)
- Has INCLUDE option that can take settings from other scripts (suitable for making scripts with default options etc.)
- Compression can start automatically by doubleclicking on a script file - autostart can be made in a "silent" mode (with or without icon in tray to indicate that ScriptZIP works)
- Scripts are plain ASCII files that can be written in any ASCII editor (NOTEPAD, EDIT ...) or created directly from ScriptZIP
- Supports drag&drop - script file can be "dropped" to ScriptZIP window
- Suitable for useage from BATCH files - after compression, it returns result code (errorlevel)
- Logging to file supported
- Support encryption (password protection) of resulting ZIP
- Everything is configurable - from initial directory where compressing starts to directories where ScriptZIP will make backup copies, temporary and log files etc.
- It can automatically test resulting ZIP after successfull compressing
- After compression, ScriptZIP can start desired executable file (EXE, BAT ...) like WINZIP, some BAT file etc.

AJ TZip was designed to be a non-visual component to support PKZip compatible compression and decompression AJ TZip was designed to be a non-visual component to support PKZip compatible compression and decompression. You will be able to create zips, convert zips to exe or exe to zips.
System requirements:
- Delphi 3 / Delphi 4 / Delphi 5 / Delphi 6 / Delphi 7
