Windows 7, Windows 8, 8.1, 10, and Vista include a built-in functionality in Disk Management to shrink and expand partitions. No more 3rd party utilities needed! It’s worth noting that many third-party utilities will be more feature-rich, but you can do the very basic stuff in Windows without adding anything new.

Windows 7，Windows 8、8.1、10和Vista在磁盘管理中包含一个内置功能，以缩小和扩展分区。 不再需要第三者公用程序！ 值得注意的是，许多第三方实用程序将具有更多功能，但是您可以在Windows中完成非常基本的工作而无需添加任何新功能。

如果您使用的是Windows 8或8.1，则需要使用“开始屏幕”搜索。 如果您使用的是Windows 10，则只需使用“开始”菜单或“控制面板”搜索。 无论哪种方式，都会发生同样的事情。

如何缩小分区 (How to Shrink a Partition)

In the Disk Management screen, just right-click on the partition that you want to shrink, and select “Shrink Volume” from the menu.

在“磁盘管理”屏幕中，只需右键单击要收缩的分区，然后从菜单中选择“收缩卷”。

In the Shrink dialog, you will want to enter the amount you want to shrink by, not the new size. For example, if you want to shrink your 50gb partition by roughly 10gb so that it will now be roughly 40gb, enter 10000 into the box:

在“缩小”对话框中，您将要输入要缩小的量，而不是新的大小。 例如，如果要将50gb的分区缩小大约10gb，以使其现在大约为40gb，请在框中输入10000：

如何扩展分区 (How to Extend a Partition)

In the Disk Management screen, just right-click on the partition that you want to shrink, and select “Extend Volume” from the menu.

在“磁盘管理”屏幕中，只需右键单击要收缩的分区，然后从菜单中选择“扩展卷”。

On this screen, you can specify the amount that you want to increase the partition by. In this case, I’m going to extend it back to the roughly 50GB size that it was before.

在此屏幕上，您可以指定增加分区的数量。 在这种情况下，我将其扩展回之前的大约50GB大小。

Note that the extend partition feature only works with contiguous space.

请注意，扩展分区功能仅适用于连续空间。
