Gary,
Now that you have located the .pst files,you have two options. You can open the archive file by selecting file > Open data file. navigate to the location of the .pst and open it. this will show up under Archive within your folder list.
Secondly, you can import the content by selecting File Import / export > Import data file (.pst)
