Not to my knowledge. It actually sounds to me like a code issue. Are you using file_put_contents() with the parameters in reverse order, by chance? If you can show the write portion of the code in your iteration, as well as a sample of the naming convention, it may offer more clues. In any case, either disk space or inode exhaustion is likely the reason things borked-up for you. -- </Daniel P. Brown> Network Infrastructure Manager http://www.php.net/
