7-Zip – Freeware File and Folder Compression and Encryption Tool [groovyDownload]

7Zip Logo ::

Today after upgrading to the latest release of 7-Zip on my machine, I decided 7-Zip deserved an honorable mention since I’ve not spoken about the product here on groovyPost (I know… long overdue!)

Similar to (which works with Windows 7 YAHOO!!), 7-Zip is one of those applications I install immediately after building a new PC.  Although 7-Zip is a Freeware application, it’s truly a feature rich WinZip replacement which provides top notch File and Folder compression and decompression for a wide range of formats including the ability to extract files from the popular disk image .ISO format.

Here’s a complete breakdown of all the main features of 7-Zip

    • Supported Operating Systems (OS)
      • Windows 98/ME/NT/2000/Xp/Vista and Windows 7 (32-Bit and x64 64-bit)
      • Windows Server 2000/2003/2008 (32-Bit and x64 64-bit)
      • Posix/Linux
      • Mac OS and other OS’s (Unsupported but available for Download)
    • Supported formats:
      • High compression ratio in new 7z format with LZMA compression
      • Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR
      • Unpacking only: ARJ, CAB, CHM, CPIO, DEB, DMG, HFS, ISO, LZH, LZMA, MSI, NSIS, RAR, RPM, UDF, WIM, XAR and Z.
    • 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 74 languages


Being the 7-Zip integrates with the Windows shell, using 7-Zip is as simple as selecting the files or folders you want to compress (or decompress) then Right Click to get the Context Menu.  Left Click on 7-Zip for all the options.

7-Zip Compress and Encrypt using AES 256 encryptionAnother feature I want to highlight with 7Zip is the Strong AES-256 Encryption available when compressing files / folders etc..   This is a GREAT feature when you need to send someone confidential information / files over the internet but don’t want to just send them clear text in an email.  Compressing the files FIRST with encryption will greatly increase the security of the files your sending PLUS, it will allow you to send just 1 file instead of many since 7-Zip will create a single file.  Easier to send, more secure and faster since the compression technology reduces the amount of data being sent.

I talked about this method of a year or more ago.  Winzip still works however 7-Zip Vs. Winzip…  Sorry, 7-Zip is free and Winzip is not.  🙂

    One little tip for 7zip users: for successful enabling file associations on Windows Vista/7, run the archiver with the administrator rights (right click on an executable/shortcut -> then choose “Run as administrator”)

    7-zip is a wonderful tool, but it seems to be very difficult for developers to really get a good email intergration.
    Several fora have discussions going on about this so called “bug”, but no one seems to bother anyway!

    Okay, it’s free, but dont put features in a program if it doesn’t work at all !!

    7-zip sucks at this point.
