7-Zip Portable

CNET Editors' review

Portability enhances this simple drag-and-drop freeware file archiver. 7-Zip Portable's plain seven-button interface makes the app quick to learn and easy to operate. Help is short and sweet, but additional information is available online.

Adding files to an archive is easily accomplished by dragging them to the program's interface. Drop a file and the Add to Archive display opens with various user options. You can pick from five formats, from the traditional ZIP to 7-Zip's own. There are six compression levels, three compression methods, 13 dictionary sizes, 12 word sizes, 20 block sizes, and CPU threading. The screen also allows you to easily enter passwords for encryption, split the archive into volumes, update, freshen, replace, or synchronize files. All options can be quickly set from pull-down menus, or left as default for faster archiving.

Decompression isn't readily available with drag and drop, but 7-Zip uses a standard file browser to choose files. Extracting is a mere matter of clicking the file to copy from the archive and pressing one button. By default, the app copies to the same folder, or you can click another button to open a file browser. The process is intuitive and fast.

7-Zip Portable fits easily on a USB drive, operates flawlessly, and will satisfy all basic archiving needs. Novices will find it easy to use, and experienced users will like the program's many easily set options.

    "Excellent! Universally useful with minimal fuss and requirements"

    May 22, 2008  |   By weyrleader

    Version: 7-Zip Portable 4.57

    Pros

    Multi-format capable (zip, rar, ace, etc) built-in; Lightweight, uses little disk space and system resources; Fast, even in the highest compression rating (often better than WinRAR's & WinZip's best - from my experience at least) it is reasonably fast and at lower compression settings it flies; Free, the price can't be beat; Multi-OS, can be used on Linux, Windows (9x, 2k/XP and Vista), and OS X; automatic and customizable sizing for breaking an archive into pieces when compressing (can make them all CD-ROM sized to burn to disc, or Zip-100 sized, or just to 136MB if you wanted to); and there's additional "plug-in" type options on their site for a range of other formats and features.

    Cons

    The OS X version is less GUI-capable (oddly since OS X is VERY GUI-centric) but there's an "EZ 7z" application/add-on to fix that. Other than this - no draw backs. It's simply a great (de)compression and archiving tool that should be a "must have" for everyone with files to archive or compress for sending across the wire.

    Pros

    I have used 7 ZIP on my desktop for a year or so and I must say I am very pleased with it performance I like better then WINZIP which I have used for more then ten years. 7 Zip is fast and does all the things I need it for. You can't go wrong with this one. Plus it’s FREE...
