If your Windows computer does not have the extraction program supplied by Microsoft, you can search for and obtain one on the Internet, such as 7-Zip. You can download the 7-Zip application at: http://sourceforge.net/projects/sevenzip/files/7-Zip/9.20/7z920.msi/download.
On the C:\ drive, all the files are restored into the original folder structure they were backed up from. This will take some time because the files are uncompressed as they are copied. In the process, any folders that did not exist are created.
Next Steps: If necessary, move the extracted files into appropriate locations on the computer. This might mean moving them into the default documents folder for your user account on the computer. It might also mean moving personal data files for email or database programs into the necessary folder.
After you are sure all your files are restored and in the correct folders on your computer, you can delete the archive package which you manually downloaded.
