Where to put static resources


My project contains many audio and video resources,where should I put them?
Say,I have a video file whose size is 1G,I want it bundled with the app.That is to say,when people install the app,he also install the video.
The problem is that I don’t know where to put the video file.I think it’s not good to put it into the root of my project.And it can’t be put into app.getPath('userData').Because only when the app running can I know what the userData directory exactly is.
I found that electron-packager has an option extra-resource which will copy a specified file into the app’s Contents/Resources,but the option is darwin/mas only and I have more than one static resource.
Are there any suggestions?
