Unzip (Uncompress) Files and Folders with Windows XP or Vista
You can unzip a file a few different ways.
Double-click the Zipped File
The easiest way to unzip a file is to double-click it. A window with the zipped files contents will open. You can click Extract all files or drag the files out of the window to the desired location (example: the desktop).
If you choose to click extract all files, the files will be extracted (unzipped) in the same location as the original file unless you specify a location in the Select a Destination and Extract Files box that appears when you choose to extract them.
Right-click the Zipped File
Right-click the zipped file and select Extract all. The Select a Destination and Extract Files window will open and let you choose if you want to save the files in the same location as the original zipped file or you can choose where you want to save the unzipped files by clicking browse and choosing a new location.
Alternatively you can use compression software such as Winzip or Winrar.
If you have a Mac
