The bundled examples saved the uploaded files to a temporary folder, but not to the destination folder. Your example does, though I removed the ''savefiles1'' for it to work.

I'm testing this locally, but it's not working for me. The script tells me (the user) that files upload successfully, but the 'savefiles' folder remains empty. Changing the name of the 'savefiles' folder also doesn't throw an error, the files still, seemingly, uploading successfully, but without actually uploading.
