In Windows kernel programming, I want to iterate through each disk, then iterate through all volumes on those disks, and finally print out the file paths of all files on each volume. How can I do this?

VOID GetAllDisk2() {
    NTSTATUS status;
    PZZWSTR deviceNaems = NULL;
    UNICODE_STRING str1;
    DEVICE_OBJECT deviceObject;
    FILE_OBJECT fileObject;
    WCHAR wcstr[512];
    ULONG index = 0;
    ULONG ltmp1, ltmp2;
    MM_COPY_ADDRESS mmAddress;

    status = IoGetDeviceInterfaces(&DiskClassGuid, NULL, 0, &deviceNaems);
    if (!NT_SUCCESS(status))
        return;

    str1.Buffer = wcstr;
    str1.MaximumLength = sizeof(wcstr);

    while (deviceNaems[index] != 0) {

        ltmp1 = wcslen(deviceNaems + index);
        str1.Length = sizeof(WCHAR) * ltmp1;

        mmAddress.VirtualAddress = deviceNaems + index;
        MmCopyMemory(wcstr, mmAddress, str1.Length, MM_COPY_MEMORY_VIRTUAL, &ltmp2);

        status = IoGetDeviceObjectPointer(&str1, GENERIC_READ, &fileObject, &deviceObject);
        if (NT_SUCCESS(status)) {
            // TODO ============


        }
        index += ltmp1 + 1;
    }

    KdPrint(("End insert."));
}

I tried using IorDeviceInterfaces () to obtain all DeviceNames, and then obtained the DeviceObject and FileObject for.
