Windows

Linux/Unix

• 1). Open a Terminal window. In Ubuntu Classic, you can do this by clicking "Applications," "Accessories," "Terminal." Other versions of Linux may put the shortcut in a slightly different location.
  
  
• 2). Type the following into the terminal:
  
  tar -xf file.tar
  
  Replace "file.tar" with the name of the tar file you would like to extract.
  
  
• 3). Type the following instead if the file is a gzipped tar:
  
  tar -xzf file.tar.gz
  
  You will know a gzipped tar by its ".tar.gz" extension. Replace "file.tar.gz" with the name of the archive you would like to extract.
