Uploading big files > 512MB (as set by default) — ownCloud Administrators Manual 6.0 documentation

# ownCloud Administrators Manual

# Uploading big files > 512MB (as set by default)

It’s usefull to know limiting factors, that make it impossible to exceed the values given by the ownCloud-system:

## 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

Note: The order of the following steps is important! If you swap steps 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)
- Click the “save”-Button

Open the php.ini - file

- 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

Do the following:

- Set the following three parameters inside th 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 = 16384 (e.g., to stay consistent with the example value above)

whereas the “output_buffering” has to be given in MegaBytes but as a plain figure (without size-units as ‘M’ or ‘G’)

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
