Norton Ghost ".GHO" files on DVD, can you help me understand data?

Hello! I had a problem with my computer a few years ago and I lost all of my data. However, the technician said that he backed up data to two DVD's, one with 5 .GHO files and the other with 1 .GHO file. 

 

After a search on Google, I downloaded Norton Ghost Explorer and I have been able to see what's inside the .GHO files. But it was not what I was expecting to see; here is an example of the tree view of the folders:

 

+ CDR00001.GHO

   + Fat 32 (H)

      + cabs

      + cmdcons

      + drivers

      + dualos

      + mcdsys

      + msdos

     ...

 

The list goes on like that, and I don't know if I need to do something to break it down more, or if what I am seeing is what I have?

 

I know that I had pictures and other documents, but I can't see anything like that.

 

Any help, suggestions or pointers will be hugely appreciated.

 

Thanks for your time,
