As I am developing a site with massive uploads, I am concerned of accumulating temporary files wasting space. I notice when investigating how the temporary file handling works in phpuploader that temp files are not removed by the uploader, wether the upload failed or succeded. Should I delete the temporary files my self or am I missing something?

 

I also notice, that the ->delete method of the PhpUploadedFile class does not delete the temp file. Or fail to in my specific case.
