 In Molecule, all custom functions are done using [Extension](./guides/extension). Next, let us quickly learn how to write an extended application based on the [molecule-demo][demo-url] project.

-All the codes are based on the [molecule-demo](https://github.com/DTStack/molecule-examples/tree/main/packages/molecule-demo) project in [Quick Start](./quick-start).

 After fetching the data of FolderTree successfully through `API.getFolderTree` ,we use the [`molecule.folderTree.add`](./api/classes/molecule.FolderTreeService#add) method to add and display data to the [FolderTree] component; next, monitor **the selected file** through the [`molecule.folderTree.onSelectFile`](./api/classes/molecule.FolderTreeService#onselectfile) method; finally,open the file through the [`molecule.editor.open`](./api/interfaces/molecule.IEditorService#open) method.
 
 :::caution
-Pay more attention: In reality, the **data type** returned by `API.getFolderTree` is not [IFolderTreeNodeProps](./api/interfaces/molecule.model.IFolderTreeNodeProps) type, we often need to go through a **conversion** method. The mock data of the `API.getFolderTree` function in the example can be [View](https://github.com/DTStack/molecule-examples/blob/main/packages/molecule-demo/public/mock/folderTree.json). The `transformToEditorTab` in the `handleSelectFolderTree` method is a **transformation** method, which mainly converts `file` to [IEditorTab](./api/interfaces/molecule.model.IEditorTab) type.
