Native File Browser provides an easy way to use the native File Browser on Mac and Windows.
You just call a static methods from the FileBrowser class, and it will display the file browser window for you, giving you a callback for when a file/folder is selected.

You can use the FileBrowser wrapper class if you’re developing for both Mac and Windows, this will automatically call the correct platform methods.
So, using FileBrowser.OpenFilePanel will automatically call:
– FileBrowserMac.OpenFilePanel on Mac
– FileBrowserWindows.OpenFilePanel on Windows
With that, you don’t have to take care of checking the current platform with Application.platform.

But if you want, you can use the FileBrowserMac and FileBrowserWindows classes and not use the FileBrowser wrapper class.
There’s some small differences between each platform (for example, only Windows allow to define a title), so when calling FileBrowser.OpenFilePanel(title), the title will only be used on Windows.
That’s why the FileBrowserMac.OpenFilePanel does not have a title parameter.
