AssetBundle Saving?

Hello. I’m new in AssetBundling.

function Start () {
        var www = new WWW ("http://myserver/myBundle.unity3d");
        yield www;
        // Get the designated main asset and instantiate it.
        Instantiate(www.assetBundle.mainAsset);
    }

It downloads the cache, and saves it by the “instantiate” command? or what?

If it saves, where does it save that? Does it have an “assetbundles” directory, or it saves the datas where it was in the editor while it was built?(for eg. assets/resources and the it saves them there)

Use WWW.LoadFromCacheOrDownload if you want the asset bundle uncompressed and saved to disk. The way you currently do it relies on the web browser caching the file for you.
