Peazip Portable would be a fantastic zipping program even if it wasn't portable. The fact that it is makes it a phenomenal option to choose for zipping and unzipping your files. It's especially potent if you need the same experience on multiple computers or have a do-it-all Flash drive.
This is a portable program, so it's made to live on a USB drive and work with multiple computers without needing installation. If you have an overly sensitive anti-virus program, it might flag this app as suspicious, but ours didn't make a peep when we tested the program. We got the program to zip most file collections in a matter of seconds, regardless of which format we chose from the dozen or so that were supported. That was just with Peazip Portable's standard method of compression, but the program offers five different forms of compression, from a fast version that prioritizes speed to a very powerful version that compresses your files as much as it can without much of a care for speed. From there, you can move the file wherever you like or even e-mail it to someone from within the app. The app's layout is downright impressive in terms of style.
Most of the elements of this app are wildly impressive, though. Easily put, Peazip Portable is one of the best zipping utilities you can find for Windows. It's even more impressive, since it can sit quietly on a Flash drive.
PeaZip Portable is the ideal package when you want to use a free file archiver and compressor utility without modifying your system, either because you prefer native portable software as replacement of installable software, or you need to bring it with you on an USB stick, or when you cannot modify the machine you are working on, or if you just want to try it without installing anything on the system: simply extract and use PeaZip, and simply delete its folder to remove the application. Compress to 7Z, ARC, BZ2, GZ, PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ, ZIP format. Read (open, view, extract) 200+ archive types: ACE, ARJ, CAB, DMG, ISO, LHA, RAR, UDF, ZIPX.
Unlike most of other classic file archivers like WinZip and WinRar, PeaZip is structured as a frontend for multiple tools. It is based on solid Open Source technology of 7-Zip for handling most common archive types, and other excellent Open Source tools (FreeARC, PAQ, UPX) for supporting additional file formats and features, providing a natively cross-platform all-purpose portable zip utility with a powerful unified GUI. PeaZip supports a wide array of advanced file and archive management features (search, bookmarks, thumbnail viewer, verify hash, find duplicate files, file converter rar to zip), especially focused on security: strong encryption (AES, Serpent, Twofish), two factor authentication, encrypted password manager, secure data delete. The distinctive trait of PeaZip is the innovative and easy to use compression/extraction interface, which makes extremely simple to check and update items set for compression and extraction, integrating a full featured file manager component. Also, zip/unzip/unrar tasks created in the GUI can be easily scheduled saved as batch scripts, in order to automate backup/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.
