This question already has an answer here:

I want to setup a CMS on WP, which should contain a page, allowing to upload and download big files. We are expecting to use an Apache-server running on Ubuntu.

Assuming to adjust values, such as upload_max_filesize,

  • which parameter limit the maximum file size
  • what is the maximum possible file size (GB?)
  • Are there other CMS, which allow to upload bigger files?

    Hi and welcome to WordPress Development. "Theoretical limit": if we collect so many file servers that they form a star, that will in the end collapse under it's own weight and form a black hole. So maybe we are looking at the Chandrasekhar limit here ;-) Just kidding. I think general theoretical server questions might be better answered at StackOverflow, ServerFault or even at Physics for very interesting answers ;-) – birgire Nov 12 '14 at 10:20
  • Recommendations are out of scope. About the maximum file size: Nearly every CMS will allow you to upload whatever your server is configured for. For the parameter see the question that I bind yours too now. – kaiser Nov 18 '14 at 1:37

The Memory Limit depends on WP_MEMORY_LIMIT set by Wp_config file .So u can change the limit To higher value but Everything Depends on your Server Specifications.


You have to set

Increase your memory limit in wp-config.php.

define( 'WP_MEMORY_LIMIT', '64M' );
define( 'WP_MAX_MEMORY_LIMIT', '256M' );

Increase the maximum execution time (max_execution_time) in your php.ini file. or in .htaccess php_value max_execution_time

Or I think go for drupal where good module available like this

  • Please take your time and work on your format. Place code in codeblocks ({} on top of the editor) or backticks where appropriate. Thank you – Pieter Goosen Nov 12 '14 at 10:43
