Directory Permission in 10g Express for Windows XP

Question

I am using Oracle 10g Express on a Windows XP machine. I want to use External Tables. I created a directory(c:\Datafiles), but the Database does not have acces to it. I tried changing the Oracle Service to run from "System" to a local user, but when I do that I am unable to open the Databse Web-Page or connect to the Database using SQL Developer. I am looking for any solution that will help.
I would like to know how I can change the permission for the "System" account so that it can access the files.
OR
Where do I find the values for the right connection setting if I run the Database as a Local User.
Any help will be appreciated.
--Thanks
My code:
CREATE OR REPLACE DIRECTORY admin_dat_dir
AS 'C:\Datafiles\data';
CREATE OR REPLACE DIRECTORY admin_log_dir
AS 'C:\Datafiles\log';
CREATE OR REPLACE DIRECTORY admin_bad_dir
AS 'C:\Datafiles\bad';
GRANT READ ON DIRECTORY admin_dat_dir TO hr;
GRANT WRITE ON DIRECTORY admin_log_dir TO hr;
GRANT WRITE ON DIRECTORY admin_bad_dir TO hr;
I plan to use these directories for External Tables:
CREATE TABLE admin_ext_employees
(employee_id NUMBER(4),
first_name VARCHAR2(20),
last_name VARCHAR2(25),
job_id VARCHAR2(10),
manager_id NUMBER(4),
hire_date DATE,
salary NUMBER(8,2),
commission_pct NUMBER(2,2),
department_id NUMBER(4),
email VARCHAR2(25)
ORGANIZATION EXTERNAL
TYPE ORACLE_LOADER
DEFAULT DIRECTORY admin_dat_dir
ACCESS PARAMETERS
records delimited by newline
badfile admin_bad_dir:'empxt%a_%p.bad'
logfile admin_log_dir:'empxt%a_%p.log'
fields terminated by ','
missing field values are null
( employee_id, first_name, last_name, job_id, manager_id,
hire_date char date_format date mask "dd-mon-yyyy",
salary, commission_pct, department_id, email
LOCATION ('empxt1.dat', 'empxt2.dat')
REJECT LIMIT UNLIMITED;
Now when I call (From Hr schema)
SELECT *
FROM ADMIN_EXT_EMPLOYEES
I get the following errors:
ORA-29913 : error in executing ODCIEXTTAVLEOPEN callout
ORA-29400: data cartridge error
KUP-04080: directory object ADMIN_LOG_DIR not found
ORA-06512: at "SYS.ORACLE_LOADER", line 19
I did some reading and found that this error is because Oracle does not have acce to the directory:C:\Datafiles\log
So I come to the problem, how do I grant access to Oracle.

Answer 1

I just checked the permission on my Folders, after following your advice. Thanks for the link.
The "SYSTEM" account has permissions to the folder, and I still see an error:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-04080: directory object ADMIN_LOG_DIR not found
ORA-06512: at "SYS.ORACLE_LOADER", line 19
