How do we refer Sub directories using UTL_FILE command

Question

Hi Gurus,
I have created a DIRECTORY My_project using CREATE DIRECTORY COMMAND. This directory is linked to my OS D:\My_project folder.
There are several sub directories under My_project folder such as D:\My_project\Outfile folder which I would like to refer while using UTL_FILE command to process files.
When I try to run the following PLSQL
DECLARE
out_file utl_file.file_type;
l_line VARCHAR2(100);
BEGIN
out_file :=UTL_FILE.FOPEN('My_project\Outfile','abc.txt','w');
l_line := 'HELLO TESTING';
utl_file.put_line(out_file,l_line);
UTL_FILE.FCLOSE(out_file);
EXCEPTION
WHEN no_data_found then
UTL_FILE.FCLOSE(out_file);
when others then
raise_application_error(-20912, 'Others ' ||sqlerrm);
END;
I get
ORA-29280: invalid directory path
error.
As there are many directories involved under My_project folder and there will be new directories created in the future as well, so I was wondering if there is a way to read files from any sub directory of My_project directory
Please advise. Thanks for all your help.
