How to install sample data with no XML file and no SQL dump file

Hi everyone,

This is my second time that I installed a template of wordpress. First time i used the dump .sql file to intall the sample data so that i only had to modify minor things. With the theme that i am using now there are no sql file and no xml files. But if i open the zip file i see maps like admin, css, js and some several .php files. Can anyone tell me how i can install these sample data files with no dump file or whatsoever.
