As for Xcode 4 version control, what does it mean when there is a question mark next to the file that you just added to the project?

Question

How do you modify it to make sure the file is correctly added?

I copied some files to the project folder. Then in Xcode, I clicked on a group and selected "Add files to project ...". Then I selected some files.

One of the files was added correctly - next to it was "A". Another file has a "?" mark next to it.

Why hasn't he added correctly? What to do to add it correctly? This is a PNG file.

What? mark means that the file is not under source control (but is part of the project). You can add it to the project by clicking on the file ---> Source Control ----> Add.
