The message is displayed to the user whose access rights lack read access permissions at the very moment an attempt to gain read access is made.

Also, you can define additional parameters, such as:
Blocked Message Caption - The text to be displayed as a caption.
Blocked Message Text - The main text of the message.
The following macros can be added to the message caption and/or message text to make the message more meaningful to the user:
%FILENAME% - Inserts the name of the file to be read.
%DEVICE% - Inserts the name of the device (e.g. USB Mass Storage Device) received from the system.
