All "files" in root on HTML5 export

Why are they all in the root? Please consider mapping ext. jpg,png,etc. to a subfolder in the C3 generated images folder, called something like files, and *.css into a folder called css. This is not best practices to have a huge mess of disparate files sitting in the root.

It has been like this since Construct 2.

You can move files into sub-folders after the export. But you will have to change paths to these files in your events. For example, instead of Load "image.png" you'll have to use Load "Pics/image.png"

There is a System condition "Is in preview" you can use to make sure your game works correctly both in preview and when exported:
