Thank you for contacting us. You can add additional extensions for the "File Upload Fields":
You may also set the "Max File Size". FYI the default file size is 1MB(1024). You should add allowance to the Max Size if your intentions are videos that can be large on some occasions. Our servers would only accept up File Sizes up to 1GB(1048576) per each file. Your form might stop working if you set it above that limit.
If you require further assistance, please do not hesitate to ask.
