Uncompress bz2 file from command line on Windows


Is there any tool in the Windows command line that allows me to do this? Otherwise, is there any light and portable application that will allow me to?

Related question, can I rename .bz2 extension to .zip? Seems to work for WinRar.

Windows doesn't have native support for .bz2. 7-zip however is free and pretty light as well as featuring command line running. The command you need for it is:

7z x archive.bz2

Sweet. Is there a portable 7z build that you know of? I want to use it just once for uncompressing a file and then delete it. – Sergio Basurco – 2015-01-14T16:04:43.010

Goto the download page on the left and in the second box (stable build, not beta) there are a number of links including a zip version - it's the 6th link down. – Andy – 2015-01-14T16:07:42.930

As it is not apparent: 7-zip is both a command line and GUI utility. Easy 7-zip is very similar, with slightly improved GUI features.

The official bzip2 command line utility is available for Windows.


  1. Download and unpack the file bzip2-1.x.x-win-x64.zip for a 64 bit Windows, or bzip2-1.x.x-win-x86.zip for a 32 bit Windows.

  2. Install msvcr120.dll according to the instructions:

    All binaries depend on the Visual Studio 2013 C Runtime Library (msvcr120.dll). This can be installed using the Visual C++ Redistributable Packages for Visual Studio 2013 installer.
