Windows 8.1双启动无法调整Windows分区的大小

我正在制定的分区方案分别为Windows 8.1和Ubuntu提供80GB，目前Windows仍在占用400GB，现在我正尝试将其大小调整为177GB。尝试使用Windows默认分区管理器，它只能缩小50GB。进行碎片整理后，又获得了20GB左右的存储空间。在这个70GB的分区上安装了Ubuntu，并运行GParted来进一步缩小Windows，但没有运气。我得到这个：

GParted 0.18.0 --enable-libparted-dmraid --enable-online-resize

Libparted 2.3

有什么办法可以解决Windows上这些“无法移动的文件”的问题？预先感谢大家！
