When using a database server like MySQL you should not bother! Depending on the Storage Engine used there may be one or more files for each database (MyISAM) or just one file (InnoD:cool:. The storage is controlled by the server code, and you should not attempt to access any database object from the file system at all.
The SPSs are stored 'somewhere inside the database file(s)', there is no other way to access them than using a MySQL client.
