Vaults with Automatic Folder Creation
Automatic folder creation functionality enables the File Server or system administrator to create vaults that manage their own folders using a threshold based on the number of files. The system automatically creates disk folders as necessary under a root folder. Root folders are folders that automatically manage their own folders.
* 
The first time you register the File Server and no folders exist under the root folder, the first physical folder is automatically created under that root folder.
This functionality decreases the maintenance effort for administrators and enables more efficient use of the space allocated to the Windchill file vaults.
