Ektron CMS400.Net Reference
If this option is enabled, each time a new content/library folder is created in Ektron CMS400.NET, a corresponding physical folder is created on the file system. This helps organize library assets on your file server.
The following illustration compares the library folder tree with the file system’s folder structure.
Note: If upgrading, the installation does not the create sample Web site’s folders on the file server. These folders must be added manually. However, all folders created by you are also created on the file server when enabled.
