Default Recovered lost data files, trying to get the Texts into a readable format

So I followed the guide on the sticky here on the forum for recovering lost data. Everything worked out great, and I now have a load of recovered data in a folder on my desktop.

My goal here is to recover some text messages from August of 2013. Some of the pictures that I saw on there are from before then, so I'm hoping there's a chance it's not overwritten.

My problem:
I have a ton of files on here that have weird extensions, I can't open them, and I'm not really even sure what to look for to get to these text messages, or get them into a readable format. Any help here is appreciated!
