Download File with specific user access

Hi Support,

This looks like an amazing plugin that i need for my organisation.

My current website environment: My website allow any users to register an account (A simple WP user registration). When user log in to their account, they will have their own "My account page" that allows them to download their pdf files. All the pdf files are uploaded by my admin and must set access to specific user only. Means that specific user can only view/download their pdf file only when they logged in. All the pdf files are very confidential and cannot be access by public and only accessible by specific user after they log in. Users can only download files when they log in to their account, they are not allowed to change or upload file.

My question is:

1. Are this plugin able to set file download access to specific user with registered user account?

2. Are the files uploaded to this plugin protected and secured? Meaning if someone knows the file direct url, he cannot use the link to download the file.

3. Are this plugin integrated to wp user account or other user profile management plugin?
