How to get file name by its unique id?

I have unique id of a MSword file.I want to know the name of this word file and location,where this file is stored by this unique id. Thanks in ad开发者_运维问答vance

My guess would be a query in the database you got the ID from: SELECT path FROM documents WHERE id = @whatever

(btw, I also voted to close as "Not a real question")
