The Smart Folders functionality is installed using an Alfresco Module Package (AMP). However, after the installation of the AMP, the feature is not active by default. To use Smart Folders, a system administrator must explicitly enable the function by setting the smart.folders.enabled property to true in the alfresco-global.properties file and then restarting the Alfresco server. A failed attempt to create or apply a Smart Folder is a direct symptom of this default-disabled state.

A. The site manager created a template first.

Creating a template is a prerequisite for applying a Smart Folder structure; it is a necessary step in the process, not a cause for failure.

B. Smart Folders can only be created by Site Administrators.

This is incorrect. Applying a Smart Folder template is governed by standard folder permissions; users with edit permissions on a folder (e.g., Site Manager, Collaborator) can apply the template.

C. The Smart Folder AMP has not been installed.

While a missing AMP would make the feature unavailable, the more specific and common cause of failure after installation is that the feature remains disabled by its default configuration.

1. Alfresco Content Services 7.0 Documentation, "Configuring Smart Folders": This official documentation explicitly states the default configuration.

Reference: "You can enable or disable the Smart Folders feature by setting the smart.folders.enabled property to true or false in the alfresco-global.properties file. You must restart the Alfresco server for the setting to take effect. By default, this property is set to false."

2. Alfresco Content Services 7.0 Documentation, "Applying a Smart Folder Template": This page clarifies the permissions required, refuting option B.

Reference: Under the prerequisites for applying a template, the documentation states: "Ensure you have the correct permissions to edit the folder." This indicates standard permissions are used, not a role exclusive to Site Administrators.
