public class FilesRESTServices extends Object
FilesRESTServices provides the server-side implementation for managing files and folder assets in a file system. Notice that the integrator identifiers are not specified for the file system because the files can be changed by so many processes. If the files are being controlled by an application then use the ContentManagerRESTServices

      public GUIDListResponse createFolderStructureInCatalog(String serverName, String userId, String parentGUID, PathNameRequestBody requestBody)
      Creates a new folder asset for each element in the pathName that is linked from the parent entity. For example, a pathName of "one/two/three" creates 3 new folder assets, one called "one", the next called "one/two" and the last one called "one/two/three".
      Parameters:
      serverName - name of calling server
      userId - calling user
      parentGUID - root object to connect the folder to
      requestBody - pathname of the folder (or folders)
      Returns:
      list of GUIDs from the top level to the leaf of the supplied pathname or InvalidParameterException one of the parameters is null or invalid or PropertyServerException problem accessing property server or UserNotAuthorizedException security access problem.
