That is usually an intentional design of the security of the operating system. For example if you don't have access rights to a file and you also have no rights to list files in the parent folder, then you are not allowed to know if the file exists or not, therefor the error given is not access denied, but file not found. An Access denied error would leak knowledge about the existence of a file. However if you would have rights to list files in the folder, but no read and write rights on the file, you might get an Access denied instead. However, Firebird simply communicates the error given by the Operating System. Mark -- Mark Rotteveel
