In Oracle SQL Developer, I started to write a script which will take the result of a query, format data and write modified data to txt file (position field file)

```
declare
  ...
  out_file UTL_FILE.FILE_THYPE;
begin
  out_file := UTL_FILE.FOPEN('C\USER\BOB', 'TEST.TXT' 'W');

  ...
end

```

I always get

> 
> invalid directory path, a corresponding directory object does not
> exist
> 
> 
> 

tried

```
 out_file := UTL_FILE.FOPEN('C:\TEMP', 'TEST.TXT' 'W');

```

but get same result, file and folder exist
