Loading subassets at runtime

Is it possible to load all subassets of a file path just like AssetDatabase.LoadAllAssetsAtPath does, just for runtime?

Resource.LoadAll usually only loads all files from a folder and simply returns the asset at the path if it points to a file, and ignores it’s subassets.

Do you know any other alternative I can take a look at?

Check out Asset Bundles. You can basically create a package of assets, then load them all in at once, and pick and choose the ones you need.
