如何在 Windows 10 中加密文件夹(How to Encrypt a Folder in Windows 10)
根据您要加密的内容，可以使用不同的文件夹加密软件。(encryption software)Windows 10 为此提供了两个内置工具，即EFS 和 Bitlocker(EFS and Bitlocker)。EFS代表加密文件系统(File System)，用于加密单个文件和文件夹，而Bitlocker用于加密整个卷。除了这些本机工具之外，互联网上还有大量第三方加密应用程序可提供附加功能。
方法 1：在 Windows Enterprise 和 Pro 上使用加密文件系统
(Method 1: Use Encrypting File System on Windows Enterprise & Pro
)
通常情况下，用户只希望保护某些文件免受侵犯隐私的兄弟姐妹或嫉妒的同事访问他们的计算机。如果确实如此，那么第一步是创建单独的用户帐户，然后拒绝其他用户访问您的个人文件。这可以通过使用EFS 功能(EFS feature)来实现，该功能基于每个用户加密NTFS驱动器上的数据。(NTFS)
- 通俗地说，只有加密文件的用户帐户(user account)才能访问它们。并且，将禁止所有其他帐户与加密文件进行交互。
- 您只需从该用户帐户(user account)登录即可访问文件，无需再次输入加密密码(encryption password)。
- 不过，请务必为您的用户帐户设置一个强密码，因为这是访问您的加密文件和文件夹的其他人之间唯一的区别。
注意：(Note: ) EFS 仅适用于Windows的(Windows)Enterprise 和 Professional 版本(Enterprise and Professional versions)。
按照下面列出的步骤使用EFS加密(EFS)Windows 10中的文件夹。
Step I: Encrypt File/Folder using EFS
1.同时按Windows key + E keys打开文件资源管理器(File Explorer)
2. 右键单击要从其他用户加密的文件，然后从随后的菜单中选择“属性”，如图所示。(Properties )
3. 在“常规(General)”选项卡上，单击“高级...”(Advanced… )按钮，如下所示。
4. 最后，选中压缩或加密属性(Compress or Encrypt attributes )部分下的加密内容以保护数据(Encrypt contents to secure data)选项框。
5. 单击确定(OK )保存修改。
6. 如果是对单个文件进行加密，会弹出加密警告对话框。(dialog box)选择任一给定选项(options)并单击OK。
- 加密文件及其父文件夹（推荐）(Encrypt the file and its parent folder (recommended))
- 仅加密文件(Encrypt the file only)
7. 单击属性窗口中的(Properties)应用(Apply )以应用更改。
8. 这将打开一个窗口，提示您选择加密选项。选择您的首选选项(option)，然后单击“确定(OK )”继续：
- 仅将更改应用到此文件夹 (Apply changes to this folder only )
- 将更改应用到此文件夹、子文件夹和文件(Apply changes to this folder, subfolders and files)
注意：在(Note:)加密过程中(encryption process)，窗口可能会冻结一会儿。
9. 单击确定(OK )退出文件夹属性窗口。加密文件将在文件缩略图的右上角标有一个小挂锁，如图所示。
第二步：设置和保存加密密钥
(Step II: Set & Save Encryption Key
)
10. 文件/文件夹加密成功后，屏幕右下角会出现要求您备份加密证书和密钥的通知。(encryption certificate and key)打开此通知(notification)并选择立即备份（推荐）( Back up now (recommended))选项以继续。
注意：(Note:)您也可以选择其他选项，但我们建议您立即备份以防止任何类型的数据丢失，以防您忘记用户帐户密码(user account password)并且将来无法访问加密文件。
11. 按照证书导出向导中(Certificate Export Wizard)的屏幕说明( on-screen instructions)进行操作。输入密码(Password)和确认密码(Confirm password)并单击下一步(Next)。
12. 单击浏览...(Browse…)按钮选择应保存加密密钥(encryption key)的确切位置并为其设置适当的名称(appropriate name)。
13. 单击下一步(Next)以完成它。
就是这样，您已成功加密来自其他用户帐户的文件，并为安全起见保存了恢复密钥(recovery key)。
注意：(Note:)建议将恢复密钥(recovery key)和加密证书(encryption certificate)复制到外部媒体或上传到云存储。
以后要解密文件，请按照步骤 1-4( steps 1-4)打开文件的高级属性窗口(Advanced Attributes Window)。只需取消选中加密内容以保护数据(Encrypt contents to secure data )选项，如下所示。

Encrypting data prevеnts it from being viewed by other users who have access to thе same computer. In this article, we haνe explаined two solutions on how to encrypt a foldеr in Windows 10 in order to protect your files on Windows 10. So. continυe reading to encrypt a file using folder encryption software.
How to Encrypt a Folder in Windows 10
Depending on what you are looking to encrypt, there are different folder encryption software that can be used. Windows 10 offers two built-in tools for this purpose, namely, EFS and Bitlocker. EFS stands for Encrypting File System and is used to encrypt individual files and folders whereas Bitlocker is used to encrypt entire volumes. Apart from these native tools, there are also a plethora of third-party encryption applications available on the internet which offer additional features.
Method 1: Use Encrypting File System on Windows Enterprise & Pro
More often than not, users are only looking to protect certain files from their privacy-invading siblings or envious colleagues who have access to their computer. If that is indeed the case, making separate user accounts is the first step followed by denying access to your personal files to other users. This can be achieved by using the EFS feature which encrypts data on NTFS drives on a per-user basis.
- In layman’s terms, only the user account that encrypted the files will be able to access them. And, all other accounts will be prohibited from interacting with the encrypted file.
- You simply need to log in from that user account to access the files and need not enter the encryption password again.
- Although, be sure to set a strong password for your user account as that is the only thing that stands between others accessing your encrypted files and folders.
Note: EFS is only available on Enterprise and Professional versions of Windows.
Follow the steps listed below to encrypt a folder in Windows 10 using EFS.
Step I: Encrypt File/Folder using EFS
1. Press Windows key + E keys simultaneously to open File Explorer
