Claim listing using Ninja Forms in V2

Hi, I had set up the native GD claim form and that was working fine.

Now i want to add some additional fields for verification, and also ask the claiming user to upload some documents eg. ID, company incorporation documents etc.

Can i get user to upload files thru NF claim form, if so how, please?

Also, where will the information uploaded by the user get stored – ie if i ask for some addtitional information where will that get stored

thanks
Vivek
