If you want your users to receive a notification via email or J!Extranet message when you upload new files into folders, you must create a notification.

When you set up a notification, you do not specify the users who will receive it, instead, you select a list of folders for which the notification will be triggered. This way, all the users with access to those folders will receive the notification.

To create a notification, you must go to Notifications -> New.

Complete the required fields from the page.

For "Name", give a suggestive name, in my example since this notification will be sent when adding new files into folder "pictures", I've named it "Notifications for pictures".

For "Subject", enter your notification subject, if the notification will be sent via email, this will be the email subject.

For "Message", enter the actual notification body.

As a default, the notification is enabled only for back-end uploads. If you want to make it work also for front-end uploads, choose "Front-end enable" to Yes.

On the "Usage" tab view, you must choose for which folder this notification will get triggered. In other words, only when you add new files in the selected folders this notification will be sent. Of course, only users with download access to selected folder(s) will receive the notification.

Since in this example I wanted this notification to be sent when I upload files into the folder "cmh", I had selected that one.

You will also notice a select named "Recursive notification". When you select a folder, this notification will be sent only in the case of that folder. But let's say you create another folder named "test" inside "cmh" and you would like the same notification to be sent also for "test". Since when you have created this notification you have selected only "cmh", this notification will not be sent in case of "test". You could edit the notification and select also "test" and that should fix this problem, but this becomes difficult if you often add new folders. That's why, you can select choose "Yes" for "Recursive Notification" and the notification will be sent also to "test" even if you did not select it. And will be sent for whatever folder is contained by the selected folder.

The last tab is "Email subscribers". On this tab view, you can specify a list of emails to also be notified by this notification. This allows you to notify persons who are not part of your Joomla users. This only works for front-end uploads.
