How do I download and add files to project folder at runtime?

I have many SVG images , audio tracks and some json files in my game and each game level has different images, audio tracks and json files .

I want to reuse the same base game/ template for each level so that future changes are easy to apply across multiple levels.

So i want to load the relevant images/audio tracks/json files at runtime depending on the level.

How do I download and add these files to the project folder at runtime?

You could use the load from URL action directly to 'stream' the relevant content.

Otherwise you could use the browser download action or nwjs to write to content to the users local disk to retrieve later.

I am not able to do this for SVG as for SVG the image can only be set from the project folder ? Is there any way to do this?
