Furthermore, it llows reading additional information from files, such as sensor positions, anatomical MRIs, triangulated meshes, etc.Hard links. A hard link is the file-system representation of a file by which more than one path references a single file in the same volume. To create a hard link, use the CreateHardLinkA function. Any changes made to a hard-linked file are instantly visible to applications that access it through the links that reference it.The MoveFile method preserves ACEs (Access Control Entries) only when moving the file within the same volume. This includes inherited ACEs, which become direct ACEs when moved (direct ACEs take precedence over inherited ACEs). If a file is moved between volumes, ACEs will not be copied.
