It is indeed the case that right now you can only move single files with drag and drop (because currently, Move Refactoring only supports single files). However, we've not seen a case where the remaining files get deleted! That is definitely a serious bug -- if you have a reproducible test case I would strongly encourage you to file a bug or at least post the steps here. Thanks.
