I've had tons of requests from our customers and users to be able to preview the attached files before submitting the form. Let me break it down.
In our institution, we utilize the "Save my progress and resume later" feature. So for instance, one user starts the form and another completes it or it goes through multiple users that sign off on the information before submission. Most of the time there is uploaded files or pictures that are attached to the form, but once they are attached/uploaded to the form there is no way for the next user or any user to view them (See link below). At most, the user can remove the attachment which is very powerful and can be problematic for others that may accidentally remove it.
In our case, being able to see what is attached to the form before signing off or submitting is crucial. It appears that the uploaded files are in fact already on the server with an added .tmp extension and once it submitted the .tmp extension is removed.
Could this added functionality be added to the future release??
