现代版本的Windows带有一个方便的磁盘管理实用程序(disk management utility)，允许您即时创建、调整大小和删除驱动器分区，而无需启动到特定的磁盘实用程序或购买(disk utility or purchase)其他软件。我们所说的Windows内置工具叫做磁盘管理，(Disk Management,)它非常好用。如果您想对磁盘和分区进行一些更改，请继续阅读：
注意：(NOTE: )本文涵盖Windows 10、Windows 7 和Windows 8.1。在阅读之前，您应该知道我们是从您知道如何启动磁盘管理(Disk Management)的假设开始的。如果您不知道如何操作，请阅读在Windows（所有版本）中打开磁盘管理工具的 9 种方法。(Disk Management tool)
1.查看有关您的驱动器和分区的信息
打开磁盘管理(Disk Management)工具，在其顶部区域，您可以看到有关您的驱动器的信息。它向您显示在系统上找到的驱动器上创建的每个分区的名称、大小和类型。它显示已格式化的分区以及未格式化的分区，以及在您的驱动器上找到的任何隐藏驱动器或未分配空间。
但请记住，磁盘管理实用程序(Disk Management utility)只能管理与Windows操作系统兼容的文件系统，例如NTFS、exFAT 或FAT32。虽然它可以看到其他类型的分区，例如由Linux创建和格式化的分区，但它只能删除它们，不能管理它们。
2. 在您的驱动器上创建分区
如果您的硬盘驱动器上有可用空间，您可以使用它来创建一个或多个新分区。未分区的空间突出显示并标记为未分配(Unallocated )或“可用空间”。("Free space." )使用全部或仅部分可用空间创建分区的最快和最简单的方法是右键单击或点击并按住该未分配space and click/tap“新建简单卷”。("New Simple Volume.")然后，按照“新建简单卷向导”的步骤进行操作。("New Simple Volume Wizard.")
如果您需要有关如何在Windows中创建分区的详细指导，请阅读本教程：在Windows（所有版本）中创建分区的 2 种方法。
3.格式化(Format)驱动器上的分区
如果您刚刚在其中一个驱动器上创建了一个分区，分区向导(partition wizard)已经为您提供了格式化它的选项。但是，您也可以格式化已创建并存在于驱动器上的分区。如果这是您想要的，您应该记住，格式化分区意味着删除其中的所有数据，因此请确保在继续之前备份其上的所有关键文件。
要格式化现有分区，请在“磁盘管理”窗口中右键单击或(Disk Management)点击并按住(tap and hold)它，然后单击或点击“格式化(Format)” 。设置标签、文件系统类型(file system type)和分配单元大小(allocation unit size)。请注意，对于后者，保留默认单位大小(default unit size)应该是大多数用户的正确选择。
然后，Windows应该开始格式化分区。这个过程应该只需要几秒钟，但这取决于分区的大小和驱动器的速度。如果您想了解有关如何格式化固定或便携式驱动器的更多详细信息，您可能会对本教程感兴趣：在Windows中格式化(Windows)SD 卡(SD Card)、USB 记忆(USB memory)棒或硬盘分区(drive partition)的 2 种方法。
4.调整驱动器上的分区大小
您还可以缩小或扩展驱动器上的分区，只要在您尝试修改的分区之前或之后有一些可用的（未分区）空间。扩展或缩小分区都不需要格式化。
要使分区更大或更小，请右键单击或点击并按住该分区，然后根据需要单击(partition and click)或点击“扩展卷”("Extend Volume")或“缩小卷”("Shrink Volume,")。然后，如果您选择将其放大，请按照“扩展卷(Extend Volume) 向导”的步骤进行操作，或者在“(Wizard)缩小(Shrink)”对话框窗口(dialog window)中选择要使其变小。
如果您想要有关如何在Windows(Windows)中调整分区大小的分步指南，请参阅本教程：在 Windows 中调整分区大小的 2 种方法（(Windows)所有版本）。
5. 从驱动器中删除分区
如果您不再需要任何分区并且想要释放它们占用的驱动器空间(drive space)，则可以使用相同的磁盘管理(Disk Management)工具将其删除。但请注意，在删除分区之前，您应始终确保其上没有重要文件，因为其中的所有文件也会消失。
要使用磁盘管理(Disk Management)删除分区，请右键单击或点击并按住(tap and hold)它，然后单击或点击“删除卷”。("Delete Volume.")在显示的“删除简单卷”("Delete simple volume")提示中，确认您确实要执行此操作，然后删除分区。
如果您想了解有关分区删除过程(partition deletion process)的更多详细信息，我们有一个单独的分步指南：在Windows中删除分区的两种方法，无需第三方应用程序。
6.更改分区的驱动器号
磁盘管理(Disk Management)还为您提供更改驱动器号的选项。它们是每个人都可以在文件资源管理器(File Explorer)或Windows 资源管理(Windows Explorer)器中看到显示在其驱动器上的那些字母。Windows中最常见的驱动器盘符(drive letter)是“C”，因为它是操作系统(operating system)用来标记Windows 安装驱动器的(Windows installation)默认盘符(default letter)。这也是为什么您不能更改C盘的(C)盘符(drive letter)的原因，至少不能使用常规方法。🙂
要更改与分区关联的驱动器(drive letter)号，请右键单击或点击并按住该分区，然后单击(partition and click)或点击“更改驱动器号和路径(Change Drive Letter and Paths)”。
应该会弹出一个新窗口，列出分区的驱动器号。(drive letter)单击(Click)或点击更改(Change)，然后在下一个窗口中选择要分配给它的新驱动器号。(drive letter)然后，单击或点击 OK(click or tap OK)。
有关整个过程的更详细说明，您可以阅读我们发布的此单独指南：如何在Windows中更改任何(Windows)驱动器或分区(drive or partition)的盘符。
7.更改分区的驱动器标签
与更改驱动器(drive letter)号类似，您也可以使用磁盘管理工具(Disk Management tool)更改其标签。在文件资源管理器或 Windows 资源管理器(File Explorer or Windows Explorer)中查看分区时，分区的卷标显示在(volume label)驱动器(drive letter)号旁边，如果您计划与其他操作系统共享分区，也需要它。要更改分区的标签，请右键单击或点击并按住(tap and hold)分区，然后在上下文菜单中选择属性。(partition and select Properties)
在分区属性窗口的(Properties window)常规选项卡中，在(General tab)磁盘图标(disk icon)旁边输入新标签名称(label name)。
单击或点击OK，分区的标签将立即更改。如果您想了解更多为分区设置标签的方法，请查看本指南：在Windows中标记和重命名任何驱动器的 4 种方法。
您使用磁盘管理工具(Disk Management tool)吗？
或者您更喜欢来自第三方的其他软件，例如MiniTool Partition Wizard Free、EaseUS Partition Master Free Edition、Paragon Partition Manager Free或AOMEI Partition Assistant SE？我们发现磁盘管理(Disk Management)实用程序易于用于管理分区，但有些人可能不这么认为。您对分区有任何提示，或者您想对一些好的分区设置提出一些建议吗？如果您这样做，或者如果您有任何疑问，请随时在下面发表评论。
7 things you can do with the Disk Management tool, in Windows
Modern versions of Windows comе with a handy disk management utility that allows you to create, resize and delete drive partitions on the fly, without having to boot intо a particular dіsk utility or purchaѕe additional software. The Windows built-in tool we are talking about is called Disk Management, and it is quite easy to use. If you want to make some changes related to your disks and partitions, read on:
NOTE: This article covers Windows 10, Windows 7 and Windows 8.1. Before reading it, you should know that we start from the assumption that you know how to start Disk Management. If you do not know how, read 9 ways to open the Disk Management tool in Windows (all versions).
1. See information about your drives and partitions
Open the Disk Management tool and, on its top area, you can see information about your drives. It shows you the name, size, and type of each partition created on the drives found on your system. It displays the partitions that are formatted but also those that are not, as well as any hidden drives or unallocated space found on your drives.
Keep in mind though, that the Disk Management utility can only manage file systems compatible with Windows operating systems, such as NTFS, exFAT, or FAT32. While it can see other types of partitions, such as the ones created and formatted by Linux, it can only delete them, not manage them.
2. Create partitions on your drives
If you have free space on your hard drive, you can use it to create one or more new partitions. The unpartitioned space is highlighted and labeled as Unallocated or "Free space." The fastest and easiest way to create a partition using all or only some of the free space available is to right-click or tap and hold on that unallocated space and click/tap on "New Simple Volume." Then, follow the steps of the "New Simple Volume Wizard."
If you need detailed guidance on how to create a partition in Windows, read this tutorial: 2 ways to create a partition, in Windows (all versions).
3. Format partitions found on your drives
If you have just created a partition on one of your drives, the partition wizard has already offered you the option to format it. However, you can also format a partition that is already created and present on a drive. If this is what you want, you should keep in mind that formatting a partition means that all the data on it is removed, so make sure you backup any critical files on it before you go ahead.
To format an existing partition, right-click or tap and hold on it, in the Disk Management window, and then click or tap on Format. Set the label, file system type, and allocation unit size. Note that for the latter keeping the default unit size should be the right choice for most users.
Then, Windows should start formatting the partition. This process should only take a few seconds, but that depends on the size of the partition and the speed of your drive. If you want more details on how to format drives, fixed or portable, you might be interested in this tutorial: 2 ways to format an SD Card, a USB memory stick or a hard drive partition, in Windows.
4. Resize the partitions found on your drives
You can also shrink or expand partitions on your drives, as long as there is some free (unpartitioned) space available immediately before or after the partition that you are trying to modify. Neither expanding nor shrinking a partition requires formatting.
To make a partition larger or smaller, right-click or tap and hold on that partition and click or tap on "Extend Volume" or on "Shrink Volume," depending on what you want. Then, follow the steps of the "Extend Volume Wizard" if you chose to make it bigger, or choose how small you want to make it in the "Shrink" dialog window.
If you want a step-by-step guide on how to resize partitions in Windows, see this tutorial: 2 ways to resize a partition in Windows (all versions).
5. Delete partitions from your drives
If there are any partitions that you no longer need and you want to free the drive space that they occupy, you can delete them using the same Disk Management tool. Take note though, that before you delete a partition, you should always make sure that there are no important files on it, as everything on it is going away too.
To delete a partition with Disk Management, right-click or tap and hold on it, and then click or tap on "Delete Volume." In the "Delete simple volume" prompt that is shown, confirm that you really want to do this and then the partition is erased.
If you want more details about the partition deletion process, we have a separate step-by-step guide: Two ways of deleting a partition, in Windows, without third-party apps.
6. Change the drive letters of your partitions
Disk Management also offers you the option to change the drive letters. They are those letters that everyone sees displayed on their drives in File Explorer or Windows Explorer. The most common drive letter in Windows is "C" because it is the default letter used by the operating system to mark the Windows installation drive. That is also the reason why you cannot change the drive letter for the C drive, at least not using conventional methods. 🙂
To change the drive letter associated with a partition, right-click or tap and hold on that partition and click or tap "Change Drive Letter and Paths."
A new window should pop up, listing the drive letter of the partition. Click or tap Change and, in the next window, select the new drive letter you wish to assign to it. Then, click or tap OK.
For a more detailed explanation of the whole process, you can read this separate guide that we have published: How to change the letter of any drive or partition, in Windows.
7. Change the drive labels of your partitions
Similarly to changing drive letters, you can use the Disk Management tool to change their labels too. The volume label of a partition shows up next to the drive letter when viewing the partitions in File Explorer or Windows Explorer, and it is also required if you plan on sharing the partitions with other operating systems. To change the label of a partition, right-click or tap and hold on the partition and select Properties in the contextual menu.
In the General tab of the partition's Properties window, type in the new label name next to the disk icon.
Click or tap on OK, and the partition's label will be changed immediately. In case you want to learn more ways to set labels for your partitions, check this guide too: 4 ways to label and rename any drive in Windows.
Do you use the Disk Management tool?
Or do you prefer other software from third-parties like MiniTool Partition Wizard Free, EaseUS Partition Master Free Edition, Paragon Partition Manager Free, or AOMEI Partition Assistant SE? We found the Disk Management utility to be easy to use for managing partitions, but some might feel otherwise. Do you have any tips on partitioning or do you want to make some recommendations with some good partition setups? If you do, or if you have questions, feel free to leave a comment below.
