Would like to know if anyone could share any insight with what to do with a back-up DVD-R containing WIM format files of data. How do you extract and utilize the backed-up data? My new HP with Windows 7 got a virus recently and I was forced to restore laptop to factory condition. Resulting in of course, among other things, the loss of MS Office, i-Tunes, and other installed apps. I am re-installing of course, but wanted to ask if anyone has knowledge of what to do with the DVD I created during the back-up process prior to doing the system repair. Is this similar to a ZIP file in which I need the right application to "unzip" the data for use? Once I have MS Office re-loaded, will I need to unzip and/or reformat the data for use by MS applications and otherwise? Did this back-up and save my i-Tunes?
