The path is URL/DB and it have drwxrwxrwx attributes and the database pedido.DBF have rw-rw-rw attributes. I try to open it on write only  mode or read-write mode, but it is unabled to open. Then, I test the read only mode and it's enabled to open.
Then What's the error?

The Source Code that I used:
