Validation for Attach field max file size in web form

Trying to upload a file with a huge size(150MB) in a custom web form. But there are no validation messages showing as “Maximum file size exceed”.

Is it able to add custom validation for Attach field max size in a custom web form?

In web forms, there is a field called as Max Attachment Size (in MB). Have you used that?

Thanks for the reply.

Actually i used that, but it also not showing any validation messages if we are uploading a file with biger size.
