Compression ratio

We compared 7-Zip with WinRAR 5.20.

FILE SETS: Mozilla Firefox 34.0.5 for Windows and Google Earth 6.2.2.6613 for Windows.

Compression ratio results are very dependent upon the data used for the tests. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. And 7-Zip compresses to zip format 2-10% better than most of other zip compatible programs.

Description

The Unarchiver is a small and easy to use program that can unarchive many different kinds of archive files. It will open common formats such as Zip, RAR (including v5), 7-zip, Tar, Gzip and Bzip2. It will also open many older formats, such as StuffIt, DiskDoubler, LZH, ARJ and ARC. It will even open other kinds of files, like ISO and BIN disc images, some Windows .EXE installers. The list is actually much longer - see the program homepage for the full list.
The Unarchiver also tries to detect and correctly handle the filename encoding in the archives it opens, allowing you to open files from every part of the world without getting garbled filenames.
The Unarchiver aims to be the only unarchiving program you will ever need, and to stay out of your way.
Also, if you need to open archives on your iPad or iPhone, look for 'Archives' on the App Store, or go to https://theunarchiver.com/archives. It is based on The Unarchiver, and lets you easily handle Archives on iOS!

What’s New

We’re excited to bring you an update based mostly on your feedback. Yes, we are always listening, so keep it coming.
- We tweaked extraction settings to feel even more system-like
- Hardened Runtime was enabled
- Sentry error reporting was integrated. It will help us better identify and fix errors
Fixed:
- Parsing comments inside ZIP archives won’t result in them being extracted as zero sized files
- Sometimes, upon trying to open an especially large number of archives at the same time, The Unarchiver would crash. That has been fixed.
- The Unarchiver will now correctly identify a ZIP in a RAR and vice versa
- Parsing Extra Fields in ZIP archives was improved
- Permissions handling for Windows files is now working as expected
- Last but not least, multiple extraction errors in old archive formats are fixed and won’t bug you anymore.

Still the best.

Let’s be honest here, we’ve been through so much and Unrachiver was always there. This is the best free program to unpack/pack your files.

Still the same error 22

Can't open some ZIP files, WIN10 does it well.
Error 22.
