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.
