iBackup Viewer is a free tool for both Windows and macOS that can be downloaded from http://www.imactools.com/iphonebackupviewer/.

The tool expects the backup to be located in the default location, but you can change it to the location of your choice—for example, an external drive.

To extract the backup, observe the following steps:

1. If the backup you want to analyze is not saved in the default location, click on the Preferences hyperlink on the main screen and choose the correct location, as illustrated in the following screenshot:

2. You will see the backups available in the location you chose. Click on the one you want to examine.

You will see potential evidence sources that are available, including contacts, call history, messages, the calendar, notes, voicemails, and browsing history, as shown in the following screenshot:

3. It's important to note that you can browse the backup as a filesystem, using the Raw Data mode (the last icon in the previous screenshot), as shown in the following screenshot:

With the help of this tool, you can easily view and export files of interest. Of course, it's not the only tool capable of solving such tasks. Let's look at another one—iExplorer.
