+### Functions
+
+`NoteSync` provides three functions for synchronizing files and folders, which can be used in your own script notes.
+
+`mode` specifies the handling method when a file already exists in the target vault:
+- `pass`: Skip;
+- `overwrite`: Overwrite;
+- `mtime`: Take the latest modified time;
+
+
+```js
+let ns = app.plugins.plugins['note-sync']
+
+// 同步系统文件夹
+ns.fsEditor.sync_folder(
+	src:string,
+	dst:string,
+	mode='mtime',
+	strict=false
+)
+
+// 同步笔记文件夹
+ns.fsEditor.sync_tfolder(
+	tfolder:TFolder,
+	vault_root:string,
+	mode='mtime',
+	attachment=true,
+	outlink=false,
+	strict=false
+)
