Big File Upload Configuration (> 512MB)
The default maximum file size for uploads, in ownCloud, is 512MB. You can increase this limit up to the maximum file size which your filesystem, operating system, or other software allows, for example:
< 2GB on a 32Bit OS-architecture
< 2GB with IE6 - IE8
< 4GB with IE9 - IE11
64-bit filesystems have much higher limits. Please consult the documentation for your filesystem.
|The ownCloud sync client itself however is able to upload files of any size, as it uploads files by transmitting them in small chunks. But, it can never exceed the maximum file size limits of the remote host.|
Make sure that the latest version of PHP (at least 5.6) is installed
Disable user quotas, which makes them unlimited
Your temp file or partition has to be big enough to hold multiple parallel uploads from multiple users; e.g. if the max upload size is 10GB and the average number of users uploading at the same time is 100: temp space has to hold at least 10x100 GB
ownCloud comes with its own
Set the following two parameters inside the corresponding php.ini file (see the Loaded Configuration File section of PHP Version and Information to find your relevant php.ini files) :
php_value upload_max_filesize = 16G php_value post_max_size = 16G
Adjust these values for your needs. If you see PHP timeouts in your logfiles, increase the timeout values, which are in seconds:
php_value max_input_time 3600 php_value max_execution_time 3600
Apache module could also stop large uploads from completing. If you’re
using this module and getting failed uploads of large files either
disable it in your Apache config or raise the configured
There are also several other configuration options in your Web server config which could prevent the upload of larger files. Please see the manual of your Web server for how to configure those values correctly:
If you are using Apache/2.4 with mod_fcgid, as of February/March 2016,
FcgidMaxRequestInMem significantly higher than normal may no
longer be necessary, once bug #51747 is fixed.
Since NGINX 1.7.11 a new config option
is availabe. Setting this option to
fastcgi_request_buffering off; in
your NGINX config might help with timeouts during the upload.
Furthermore it helps if you’re running out of disc space on the
partition of your system.
For more info how to configure NGINX to raise the upload limits see also this wiki entry.
Make sure that
If your site is behind a NGINX frontend (for example a loadbalancer):
By default, downloads will be limited to 1GB due to
proxy_max_temp_file_size on the frontend.
If you don’t want to use the ownCloud
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
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
Tell PHP which temp file you want it to use:
upload_tmp_dir = /var/big_temp_file/
Output Buffering must be turned off in
php.ini, or PHP will return memory-related errors:
output_buffering = 0
As an alternative to the
upload_tmp_dir of PHP (e.g., if you don’t have access to your
php.ini) you can also configure a temporary location for uploaded files by using the
tempdirectory setting in your
If you have configured the
session_lifetime setting in your
config.php (See Sample Config PHP Parameters) file then make sure it is not too low. This setting needs to be configured to at least the time (in seconds) that the longest upload will take.
If unsure remove this completely from your configuration to reset it to the default shown in the
If all prerequisites described in this documentation are in place an
admin can change the upload limits on demand by using the
File handling input box within the administrative backend of ownCloud.
Depending on your environment you might get an insufficient permissions message shown for this input box.
To be able to use this input box you need to make sure that:
Your Web server is be able to use the
.htaccessfile shipped by ownCloud (Apache only)
The user your Web server is running as has write permissions to the files
Directory permissions might prevent write access to these files.
As an admin you need to decide between the ability to use the input box and a more secure
ownCloud installation where you need to manually modify the upload limits in the
.user.ini files described above.
Various environmental factors could cause a restriction of the upload size. Examples are:
CloudLinuxwhich sets a
Some services like
Cloudflareare also known to cause uploading issues
