Installing themes

Hello, Im new to the theme installing and would like some instructions. My version is 1.15.10 and if I go to my computer and click on network/media devices/wdtvlive I get to the wdlive and I scroll to appearance/user interface theme. I then browse to the folder. The problem is when I click on the folder it opens to the files and I do not know what file or how to select this the folder. Thanks for any help.
