Can you apply security to files?

I am looking to build an app where requests are submitted and a contract is uploaded.

Using a from this is easy and you get the record below

When we have worked on the request we will upload our form, my question is, can these files have permission applied so only the specified email address is able to access them?

Hi Barry,

What I recommend is using LFD filters. This allows you to personalise the LFD and use the logged in user email address to determine what they can see.
Take a look here

Let me know if this works or you have any further questions
