QuickTip: Good-Bye WinZip, Hello 7 Zip (and JZip).

My work laptop is a fairly beefy machine.  Dual Core Intel T7800 with 4 GBs of ram, running Vista Ultimate 32-bit.  Some firmware and OS limitations limit my effective memory addressing to 3.26 GB, but still this machine is no slouch.  I could never figure out what about my configuration caused seemingly simple operations like extracting the contents of a zipped file to take SO LONG.  I fiddled with this setting and that setting but to no avail.  Finally I got fed up and turned to the all-knowing Google. "Winzip Extract SLOW VISTA " returned a series of blog posting and user group chats complaining of similar performance.  Among the responses was a reference to 7 Zip.  A google search later I had downloaded 7 zip from here.  7 Zip is an open source alternative to winzip that is WICKED Fast.  I mean orders of magnitude faster than winzip and the window's built-in zip compression. 

 

According to the website, 7 Zip's features include

  • High compression ratio in new 7z format with LZMA compression
  • Supported formats:
    • Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR
    • Unpacking only: RAR, CAB, ISO, ARJ, LZH, CHM, MSI, WIM, Z, CPIO, RPM, DEB and NSIS
  • For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip
  • Strong AES-256 encryption in 7z and ZIP formats
  • Self-extracting capability for 7z format
  • Integration with Windows Shell
  • Powerful File Manager
  • Powerful command line version
  • Plugin for FAR Manager
  • Localizations for 69 languages

Its great to see my laptop perform the way I thought it should.  Do yourself a favor and download 7 Zip right now!

Want a better interface, but the same great compression engine?  Try JZip.  Just as pretty as Winzip, Cheaper (Free!) and Faster.

You should also look into jzip, which is "based on proven 7-zip technology" (their words) but provides a more friendly UI.

I recommend downloading the Corporate version of JZip which is also free and does not install toolbars or make changes to your computer's Registry.
The personal version is full of adware which, as Lance says, is a pain to get rid of.

In terms of the compression rate, 7Zip will always leave a smaller folder than Jzip. A lot smaller. I just wished 7zip had a right click option to compress/extract the file, like JZip and WinRAR.
