SharePoint doesn't warn when setting maximum file size greater than allowed limit

Hi FrankMartin1610 

If you need to upload files larger than 10GB to SharePoint 2016, you have two options:

1. Use Remote BLOB Storage (RBS). RBS is a feature that allows you to store large files in a separate location, such as Azure Blob Storage. This can help to improve the performance and scalability of your SharePoint farm.
2. Use a third-party solution. There are a number of third-party solutions that allow you to upload and manage large files in SharePoint. These solutions typically provide additional features, such as file encryption and compression.

Recommendation:

I recommend using RBS if you need to upload files larger than 10GB to SharePoint 2016. RBS is a built-in feature of SharePoint and is relatively easy to implement and manage.
