How to get in the file name in minifilter

Question

I'm trying to create a driver that gets the file name, I even got it with an example: DbgPrint("%ws", &FileNameInfo->Name.Buffer);

But how do I get the file name without "%ws"? Only with a DbgPrint(&FileNameInfo->Name.Buffer);?

When I try to call the function without "%ws", the minifilter returns "\", could someone help me please?

This is my code:

PFLT_FILE_NAME_INFORMATION FileNameInfo;
    NTSTATUS Status;

    Status = FltGetFileNameInformation(Data,
        FLT_FILE_NAME_NORMALIZED | FLT_FILE_NAME_QUERY_DEFAULT,
        &FileNameInfo);

    if (NT_SUCCESS(Status))
    {
        Status = FltParseFileNameInformation(FileNameInfo);

        if (NT_SUCCESS(Status))
        {
            DbgPrint(&FileNameInfo->Name.Buffer);
        }

        FltReleaseFileNameInformation(FileNameInfo);
    }

    return FLT_PREOP_SUCCESS_NO_CALLBACK;

I'm using google translator.
