File and Directory structure in Pentaho BI server ce-5.2

I am successfully using Pentaho BI server ce-5.2 in tomcat. I have installed saiku plugin and saved some .saiku files. But I am not aware of the file structure it is having, in the "browse file" section. So, anyone please tell me how to physically get the file or even at least the directory structure, so that I can fire a web service to saiku with the path like

http://localhost:8080/pentaho/conten...ue#query/open/public%3ASteel%20Wheels%3AAnalysis%3Ademo.saiku

Thanks for any help !
