File

File variables are great for collecting relevant documents within one App Record and also allowing users such as clients to provide you with copies of important documents that you might need to review, confirm or attach as exhibits.

Style

The single Style option of upload tells the variable to show the file upload widget in the user interface. Whether more than one file can be attached will depend on if the variable is Single or List of.

Accept

This property is not yet active but reserved for future use. It will allow you to limit the types of files that can be uploaded in a given field.
