I used Firebird Embedded to create my database

Only forms and reports will be created as separate documents in the Base-file. So this separate documents could appear in folders.
It isn’t possible to create folders for tables or queries with the Base file.
If you use external databases there could be the possibility to create different “schema” inside the structure of the database. This will look like folders in the table-view.
