What is the max PHP upload file size in Nextcloud?

Hello everyone.

I’m setting up Nextcloud on my OMV5 (Debian 10) docker, and I have a question regarding the max PHP upload size allowed.

Iv has seen a few tutorials online on how to increase the default PHP file upload limit from 2MB to 16GB, but I haven’t seen anyone set the limit above 16GB. Is it possible to set the PHP upload limit to 32GB or greater, for example, or will this course issue with the system?

If you know, please do let me know. I want to know the largest file size to upload over the internet to my Nextcloud.
