This is an example of image favorites, which can store data recursively and hierarchically in Treeview infinitely.

 

Description of the main fields and meanings:

Name = node name (it may be the folder name or file name, which is determined by the dirflg field value)

Dirflg = whether node is a file [false] or a folder [True]

Parentid = index number of the parent item of Node

With these three key fields, you can accurately describe the node structure position in the Treeview in the program.
