The FileSystem Object is of type FileDirectoryType as it is defined in OPC 10000-5. It provides access to a hierarchy of directories and files of the device. The structure may be read and written by the Client however the device may restrict this for specific folders or files.
This Method may be used to check the specific update behavior for a set of files. The files are identified by the NodeId of their FileType instance in the FileSystem.

This Method may be used to check if the specified set of files are valid and complete for an installation. This should also include dependency checks if appropriate.
Note: In case of Direct-Loading or Cached-Loading these checks should be part of the transfer and this method shall not be supported since it is part of the file transfer (e.g. in CloseAndCommit).

ValidateFiles(
[in] NodeId[]NodeIds,
[out]ErrorCodeInt32,
[out]ErrorMessageLocalizedText);
