I have run into a problem of file sizes maxing out on 256MB.
On PHP side I have
post_max_size set to
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' => 1073741824
Yet if I try to upload files larger than 256MB I get a modal message saying file size exceeds 256MB.
