LoadFromFile is a method used to load the tree nodes from the specified file name into the Items property. FileName is a qualified file name which contains the textual representation for the tree node hierarchy generated using SaveToFile.
Each tree node in FileName is represented using leading Tab (#9) characters for the Level in the tree node, followed by the Text for the node and an end-of-line sequence (#13#10). TTreeNode instances are created and added to the Items property when the node values are read from the file.
Use SaveToFile to store the textual representation for tree nodes in Items to a given file name.
Use SaveToStream and LoadFromStream to read and write the node hierarchy using stream-based storage.
