Maximum size for upload file in Product attribute

Hi Community,
Can anyone say what is maximum filesize allowed to upload from Product attribute on product detail page?

In admin area configuration - Maximum file size (KB) is set empty for allow maximum size but I'm not able to upload file with more than 30 MB.

NopCommerce: 4.10

Done by extend file limit in web.config file

<system.webServer>
   
   <security>
        <requestFiltering>
          <!-- This will handle requests up to 9.9 GB -->
          <requestLimits maxAllowedContentLength="999999999" />
        </requestFiltering>
   </security>

</system.webServer>
