What should we do with "questions" such as this, that are really two questions disguised as one? Flag them? Edit them? Close as "not a real question"?
It depends on if it's two questions that go hand in hand or really have nothing to do with each other. In the first case, leave it alone. In the second case, try to split it up.
Often, when this happens, you have to be quick. Once there are answers, there's rarely a point in editing the question – in that case, vote to close or flag as not a real question.
But, if there aren't answers yet, I'd propose to make a bold move and edit the question for the OP, so that the post contains only one question. For example, remove all additional unrelated questions. Show the OP how it's done, and if they really want to ask their second (or third, or fourth, …) question, they'll just post another one. Of course this is a radical change, so make sure you know what you're doing – and it might be that edits like these are not accepted when suggested by users below 2k reputation.
In any case, leave a comment telling them that questions should be reasonably scoped. Point them to the FAQ where it says that. Ask them to post another question, but mention that they should link back to the original post just in case. Maybe something like this:
Please only ask one question at a time. According to the [FAQ#dontask], questions should be reasonably scoped. This will get you more precise answers and makes it easier for others to find the topics later on. I've edited your post to remove additional questions – feel free to ask them as separate posts, and link back to this question. Thanks!
Ask the user to separate the questions out - as there are no answers this should be easy enough.
EDIT: I misunderstood - mods cannot move some answers ony al of them - so the following can't apply unfortunately - we can only ask people to duplicate them and makes it more important to catch these questions early.
If there were answers then after the questions were rewritten then you would have to flag for a moderator to migrate some answers to the new question
