Development of this module sponsored by Energy Web Design
This module was created when the need arose to offer a downloadable file to users of a site, without revealing the actual URL of the file itself. It also allows through the permissions system a method of allowing the file to only be available for download to registered users. If enabled, anonymous users will see the same dynamic link as registered users, but when they click on it they are presented with a login dialog informing them they must register to have access to the file.
What it does
Simply put, it provides a Expiring Private File Link field formatter for any file fields that you define in your content type(s).
How to use it?
After installing the module, there will now be "Expiring Private File Link" field formatter for any file fields you have.
For example, say you want to add the option for users to attach a private file download to a blog entry.
First add a file field to the blog content type. When you pick the formatter from the select box, select "Expiring Private File Link".
