Upload file size limits to 256MB I have run into a problem of file sizes maxing out on 256MB.

On PHP side I have
upload_max_filesize &amp; post_max_size set to 1GB

I've created a simple PHP script to test upload size and managed to upload 800MB file. So everything points to Craft having some limits.

In Craft CMS config file I have:

'maxUploadFileSize'     =&gt; 1073741824


Yet if I try to upload files larger than 256MB I get a modal message saying file size exceeds 256MB.
When determining the maximum upload file size, Craft first takes the php.ini file upload_max_filesize, post_max_size and memory_limit into account by getting the minimum value and only then applying the Craft maxUploadFileSize config setting.
