The size limit of files that can be sent through FedConnect is 25 MB per individual file, or 100 MB per response or message. 


For example, a user cannot submit a response that contains an attachment 40 MB in size, however they can submit a response that contains two attachments each at 20 MB in size. In addition, the user would not be able to submit a response that contains 6 attachments each at 20MB in size, as that would exceed the 100 MB submission limit.
