String 

UTL_FILE_DIR = pathname 

Static 

None 

Any valid directory path 

UTL_FILE_DIR lets you specify one or more directories that Oracle should use for PL/SQL file I/O. If you are specifying multiple directories, you must repeat the UTL_FILE_DIR parameter for each directory on separate lines of the initialization parameter file.  

All users can read or write to all files specified by this parameter. Therefore all PL/SQL users must be trusted with the information in the directories specified by this parameter. 

Note: If you list multiple values, all entries of this parameter must be on contiguous lines of the parameter file. If you separate them with other parameters, Oracle will read only the last (contiguous) lines.
