PeaZip for Windows 64 bit is a free ZIP software optimized for WIN64 systems.
The application is based on powerful and solid Open Source technology of 7-Zip for managing mainstream archive formats, and other great Open Source tools (like FreeARC, PAQ, UPX) for supporting special purpose file formats and features, in order to provide a flexible zip/unzip/unrar utility featuring a comprehensive and user friendly GUI that, unlike most archive managers (i.e. WinZip and WinRar), is natively portable and cross-platform.
Create 7Z, ARC, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ, ZIP files
Open and extract over 150 archive types: RAR, ACE, ARJ, CAB, DEB, DMG, ISO, LHA, RPM, UDF, ZIPX files.
PeaZip is localized in 29 languages and is capable of handling all most popular archive formats (150+ file types), including many encrypted archives standards, supporting a wide array of advanced file and archive management features (search, bookmarks, thumbnail viewer, hashing, find duplicate files, convert archives...), especially focused on security (strong encryption, two factor authentication, encrypted password manager, secure deletion).
The distinctive trait of PeaZip is the innovative and easy to use compression/extraction interface, more similar to CD burners interfaces rather than to a classic file compressor. This design makes extremely simple to check (and update) items set for compression and extraction, integrating a full featured file manager component.
Also, tasks created in the GUI can be easily saved and scheduled as batch scripts, in order to automate backup and restore operations, or for fine tuning, or for learning purpose, bridging the gap between the ease of use of GUI applications and power and flexibility of console.
