Uploading big files > 512MB (as set by default)
===============================================
It's usefull to know limiting factors, that make it impossible to exceed the values given to the ownCloud-system:

Not outnumberable upload limits:
----------------------------------
* < 2GB on 32Bit OS-architecture
* < 2GB with IE6 - IE8
* < 2GB with Server Version 4.5 or older
* < 4GB with IE9 - IE10

Other recommendable preconditions:
----------------------------------

* make sure, that the latest version of php (at least 5.4.9) is installed

Enabling uploading big files
============================
Note: The order of the following steps is important! If you swap steps or substeps described below, the settings may fail.

**Go to the admin section in the ownCloud-WebUI and do the following:**

* Under "File handling" set the Maximum upload size to the desired value (e.g. 16GB)
* Klick the "save"-Button

**Open the php.ini - file**

* Under Debian and derivates this file lies at /etc/php5/apache2/php.ini

**Do the following:**

* Set the following three parameters inside th php.ini to the same value as choosen inside the admin-section one step before:
* upload_max_filesize = 16G   (e.g.)
* post_max_size = 16G   (e.g.)
* output_buffering = 16384

whereas the "output_buffering" has to be given in Megabytes but as a plain figure (without size-units as 'M' or 'G')

This configurations have been prooven by test up to filesizes of 16 GigaBytes.
