Load new AssetBundle

hi all!
I’ve watched this video

of @ : my goal is relative simply: I’ve a single prefab that I use to create my single .unity3d file.
reading the code of the video I create the .unity3d file and after the creation I 've 4 files:

  • foldername
  • foldername.manifest
  • myFile.unity3d
  • myFile.manifest

now, using again the code of the video I’m able to load the assetbundle, but this, for my project is not so simple to manage… the foldername files are really necessary?

thanks again!

Have you checked this demo http://files.unity3d.com/vincent/assetbundle-demo/users_assetbundle-demo.zip ?

thanks @solkar , yes, i’ve checked but is not working with assetbundles made in other project
