+#### Load spectra and molfile files:
 ```ts
  import events from '../events';
 
-events.trigger('loadURLs', {
-  urls: [
-    'https://cheminfo.github.io/nmr-dataset-demo/cytisine/13c.jdx',
-    'https://cheminfo.github.io/nmr-dataset-demo/cytisine/1h.jdx',
-    'https://cheminfo.github.io/bruker-data-test/data/zipped/aspirin-1h.zip',
-  ],
-});
+events.trigger('load', {
+			  data: [{data:ArrayBuffer,name:file1.dx},{data:ArrayBuffer,name:file2.dx}, ....etc],
+			  type:"file"
+			}
+	       );

 ```
 
 #### Load NMRium data example:
 
 You can pass NMRium data that you get when you export the data from the NMRium or what you received from dataChange event
 ```ts
-events.trigger('load', {
-  spectra:[
-       source:{
-             jcampURL:""
-         }
-     ]
-});
+events.trigger('load', { 
+                         data: {
+				  spectra:[
+				       source:{
+					     jcampURL:""
+					 }
+				     ]
+				},
+		         type:"nmrium"
+		       }
+                  );
 ```
