The I/O Manager sends the IRP_MJ_CREATE request when a new file or directory is being created, or when an existing file, device, directory, or volume is being opened. Normally this IRP is sent on behalf of a user-mode application that has called a Microsoft Win32 function such as CreateFile or on behalf of a kernel-mode component that has called IoCreateFile, IoCreateFileSpecifyDeviceObjectHint, ZwCreateFile, or ZwOpenFile. If the create request is completed successfully, the application or kernel-mode component receives a handle to the file object.
