Allow file access to specific users in Drupal (not roles) I have historical data recorded in pdf files for our clients. Now I am developing a website (in Drupal) from where clients should be able to access this data. The problem is that i don't want this files to be available to anyone else than the user to whom the information belongs.

Since this data is periodically recorded I could store it in a specific folder for each user.
My question is that if it's possible to give access to this folders or its content to specific users in Drupal. Because the alternative would be to create a Role for every user which is not good.
Create a new content type and add fields according to your
requirement or user reference field
Disable its Front page publish option.
Create new user Role like "client".
Create view of files and add relationship or contentuxal filter
against user loggin id.
Create block view assign this block into specific region.
