ora-302000 using tex_io

gurus,

i'm trying to read all the files in a directory (windows) using text_io, so i used the host command to issue a dir and dump the result into a file w/ number as a filename. however when i read the file the ff error occur  

ora-302000 non-oracle exception.

i've search the oracle metalink and it said that this error occurs if filename exceeded the os max.# of characters for filename. but i haven't reached yet the max. w/ is 8 character for win98.

is there something wrong w/ the code?  

thanks!

here's the code:

PROCEDURE get_po IS
cnt number;
in_file text_io.file_type;
linebuf varchar2(9999);
fname varchar2(9999);
empty boolean := false;

BEGIN
 select tmp_po_no.nextval into cnt from dual;   fname := 'dir c:\argus_po\*.txt > c:\argus_po\'||cnt;   host(fname);
  fname := 'c:\argus_po\'||cnt;
  in_file := text_io.fopen(fname, 'r');
  text_io.fclose(in_file);
exception
  when others then
    msg_alert('GET_PO:'||sqlerrm,'I',false);     if text_io.is_open(in_file) then

       text_io.fclose(in_file);
    end if;
end;
