where is the function _exception_handler writing to?

|--------------------------------------------------------------------------
| Error Logging Directory Path
|--------------------------------------------------------------------------
|
| Leave this BLANK unless you would like to set something other than the default
| application/logs/ directory. Use a full server path with trailing slash.
|
*/
$config['log_path'] = '';

So mine is blank. But when I look in /application/logs/ I see a bunch of log files. The last one was written 2018-10-29. Can I hard code the path to be APPPATH.'logs/' ?
