All the digital objects stored in the dLibra library are organized in a hierarchical structure of directories. Every directory can contain any number of objects or subdirectories. Directories provide a structural order in a library. In most cases documents will be assigned to directories accordingly to their owner or e.g. to the company department they belong to.

Library structure organized in a structure of directories is visible only in administrator and editor application therefore reader does not see it. Thanks to this approach editor can freely create the structure without any influence on reader view.
