When you purchase downloads, your web browser saves the file to the Downloads folder on your computer. It will remain there unless you delete it. Many people keep all of their purchased download files in their My Documents folder where they keep all important personal files, so they can use them as often as necessary to reinstall or if they get a new computer.
