Fle Upload: Put note in Properties sectin that asterisk will allow all file types

why not mention the Asterix on that page?

I assume you are referring to the asterisk that will allow all file types. If yes, it is already in the page in step #3.

If you are referring to something else, don't hesitate to let us know and we'll be glad to make the update if necessary.

I figured that out, but this would be a great tip. Thanks. 

Thank you for pointing it out. Indeed that would be helpful. Let me forward this to our backend team so they may review.
