I have a mySQL database connected with Wordpress and Formidable. On every entries, formidable save all the field into the database as-is except for the uploaded files. In the file fields, formidable only saves a number, maybe it represents for the file ID. 
The question is how do I trace from this file ID to the file itself in the file manager? I've already know the location of the files but I do not know how Formidable indexes these files.
