I've selected storage api as my default schema (screenshot attached). If i go to mailsystem admin and try to create a new class it fails to copy the temp file to the destination because no permissions. But i have set chmod 777 on files/*. My storage api class inital container is at files/storage_public. If i switch the default schema to public it will work.

The storage api schema will come through the patch #1138052-21: File entity module compatibility
