Configuring PHP
If you don’t want to use the ownCloud .htaccess or .user.ini file, you may configure PHP instead. Make sure to comment out any lines .htaccess pertaining to upload size, if you entered any.
If you are running ownCloud on a 32-bit system, any open_basedir directive in your php.ini file needs to be commented out.
Set the following two parameters inside php.ini, using your own desired file size values:
upload_max_filesize = 16G
post_max_size = 16G
das schon versucht ^^
