Resolving "fileid=xxx" field values to actual file paths

Following a previous article of mine, The dbo.tabs.IconFile field issue, I would like to share an easy way to resolve any field that holds values of the type "FileID=xxx" (where xxx is the primary key of a record in the Files table) into the actual file path. This is especially useful when you deal with the IconFile field in the Tabs table, as well as with fields of type Image in a User Defined Table, and probably in a lot more places too.
