Once the program is launched, you will be presented with a list of existing device backups which have been detected on your computer. To access a backup, select it from the list, and hit Explore.
If an existing backup has not been detected, you can tell iBackup Extractor to look in a the relevant location on your computer by using the "Change Backup Directory..." button.
After this is done, you can start browsing through your backed-up data, and extract it onto your PC/Mac. You can browse through your Calendars, Contacts, Notes, Messages, Photos, Internet browsing history and your iPhone call logs and extract these files to your computer.
