After creation of directory of files it is possible to make their accessible to other users, not only for reading, but also for editing or writing. The editor, having the "edit" right in the list (in theme of type "List"), can execute operations with editable themes inside of it, namely he can delete, rename and copy them in other lists. The writer (with "write" right), as editor, can change the contents inside of textual theme. Writer cannot change the list of themes, rename or copy their.

Access rights help to organize data exchange for some group of people. Data may be any file, for example picture, game and so on. Data exchange is useful for the organizations supporting databases when the part of employees defines structure of tables (edit), other group enters data (write), and the third only reads them.
