23  * file system, not within the database.
24  * When an Attachment is first uploaded and stored, it is prefixed
25  * with the value of the id generated on the database insert.
26  * This filePrefix property is stored separately to smoothly
27  * handle database migrations. So even if a database export-import
28  * changes the id column values, the files within the attachments
29  * folder can be used as is, without resorting to mass renaming.
