To view SMS, MMS and iMessage content on your backup, click the Messages icon in the category list in iBackup Extractor.
iBackup Extractor displays a list of contacts with whom you have had conversations with. Clicking on the contact in the list shows the text (SMS), multimedia (MMS) messages and iMessage sent and received in that conversation.
With a contact selected and a conversation displayed, click "Extract Conversations..." in the iBackup Extractor control bar to save that conversation to your computer.
iBackup Extractor will copy the conversations into a .html file, which is saved on a folder selected by you(defaults to your computer desktop).
Each .html file containing the conversations is named after the individual contact with whom you had the conversations. You can open this .html file using a browser such as Firefox or Internet Explorer.
If your conversations also contain images or pictures (MMS), iBackup Extractor will also copy these to your computer and embed them in the .html file saved.
