Not outnumberable upload limits:¶

• < 2GB on 32Bit OS-architecture
• < 2GB with Server Version 4.5 or older
• < 2GB with IE6 - IE8
• < 4GB with IE9 - IE10

Other recommendable preconditions:¶

• Make sure that the latest version of PHP (at least 5.4.9) is installed
• Disable user quota. This means: set the user quota of the account, you are currently logged in, to “unlimited”.

This is important, because you possibly could not watch otherwise whether the desired changes take effect.

Enabling uploading big files¶

Configuring your webserver

ownCloud comes with a .htaccess - file which propagates all config to your webserver. To adapt those settings go to the ownCloud - Folder on your server and set the following two parameters inside the .htaccess file:

• upload_max_filesize = 16G (e.g., to stay consistent with the example value above)
• post_max_size = 16G (e.g., to stay consistent with the example value above)

If you don’t want to use the shipped .htaccess - file, outcomment those options there and edit them in your global php.ini file:

You can easily learn the loaded configuration file by saving <?php phpinfo(); ?> code piece into a php file and calling it with your browser. Then look for the Loaded Configuration File value.

Alternatively:

• Under Debian or SUSE and their derivatives this file lies at /etc/php5/apache2/php.ini
• On Windows, you can find this file within C:/Program Files (x86)/PHP/PHP.ini

Set the following two parameters inside the php.ini to the same value as chosen inside the admin-section one step before:

• upload_max_filesize = 16G (e.g., to stay consistent with the example value above)
• post_max_size = 16G (e.g., to stay consistent with the example value above)

Output Buffering must be turned off in .htaccess or php.ini, or PHP will return memory-related errors.

• output_buffering = 0

These client configurations have been proven by testing maximum file sizes of 16 GB:

• Linux 32 Bit: Ubuntu, Firefox => 16GB
• Windows 8 64 Bit: Google Chrome => 8GB

Note: You will need a minimum of 16GB (e.g, to stay consistent with the example value above), in your upload_tmp_dir. Normally this points to /tmp. If your /tmp has not enough space, you can change the value of upload_tmp_dir in your php.ini
