+#### 7.504 Adding a File Chooser
+
+_"For those of you wondering how to get the file browser working (chooser.browseForFileToOpen does not exist any more) without changing the library preprocessor symbols - use the async version, e.g. like this:"_ - Matthias Truxa
+
+In `MainComponent.h` -> `private:`
+
+```C++
+juce::FileChooser chooser{ "Select a file..." };
+```
+
+In `MainComponent.cpp` -> `MainComponent::buttonClicked`
+
+```C++
+void MainComponent::buttonClicked(Button* button)
+{
+  if (button == &loadButton)
+    {
+    auto dlgFlags = 
+      juce::FileBrowserComponent::openMode | 
+      juce::FileBrowserComponent::canSelectFiles; 
+
+				this->chooser.launchAsync(dlgFlags, 
+						[this](const juce::FileChooser& chooser) 
+				{
+            player1.loadURL(chooser.getURLResult());
+				});
+
+        // juce::FileChooser chooser{ "Select a file..." };
+        // if (chooser.browseForFileToOpen())
+        // {
+        //     player1.loadURL(URL{ chooser.getResult() });
+        // }
+    }
+}
+```
+
+Note: There is another method where you can add `JUCE_MODAL_LOOPS_PERMITTED=1` to your JUCE preprocessors, but this method is not suggested as any changes you make to your preprocessor might not reflect in the graders' version. This might cause your project to not function as intended.
