Windows 10 隐私设置提供文件系统^{(File System)}设置，确保除非允许，否则应用程序^(Apps)将无法访问文件系统^{(File System)}和用户文件夹，例如文档、图片、视频和本地OneDrive 文件^{(OneDrive Files)}。某些应用程序需要访问文件系统^{(File System)}才能按预期工作。在这篇文章中，我们将展示如何拒绝或允许访问“下载^(Downloads)”文件夹。

拒绝^(Deny)或允许^(Allow)访问此设备上的“下载”文件夹^(Downloads)

Windows中的所有用户都可以访问他们的个人文件夹，但应用程序必须请求此访问权限，您可以选择允许或拒绝该请求。当应用程序获得与其用户相同的权限时，它将允许他们管理其中的文件和文件夹。如果您授予应用程序权限但后来改变主意，则可以关闭对File System的访问。

在早期版本的Windows中，^(Windows)下载^(Downloads)文件夹以及文档^(Documents)、图片^(Pictures)、视频^(Videos)有一个专用设置。它已更改，如果您想拒绝或允许访问下载文件夹，则必须通过File System对其进行管理。

允许或阻止特定应用程序和服务的文件系统访问

1. 打开 Windows 设置 (Win + I)
2. 导航到隐私 > 文件系统。
3. 单击^(Click)更改^(Change)按钮，然后打开设备的文件系统^(File)访问权限。
4. 接下来，在允许应用^{(Allow Apps)}访问您的文件系统下，打开应用访问。
5. 最后，选择哪些应用程序可以访问您的文件系统。

您可以选择要允许或阻止文件系统访问的单个应用程序和服务，并将设置更改为 On 或 Off。

拒绝大多数应用程序的文件系统访问。

返回文件系统^{(File System)}部分。要完全关闭访问，请^(Toggle)关闭全局设置，但如果您想单独关闭，您可以选择在每个应用程序的基础上进行。

为什么有些应用和软件没有出现在文件系统访问隐私设置中？

从Microsoft Store^{(Microsoft Store)}外部安装的任何应用程序都不会出现在列表中。如果您从 Internet 下载程序或从USB  或DVD安装程序，则此处不会显示该程序。它们也不受 允许应用程序访问您的文件系统^{(Allow apps access your file system )}设置的影响。

注意：^(Note:)如果您尝试在与您的解决方法连接的设备上进行配置，您可能无法对其进行管理。您将在文件^(File)系统设置页面的顶部看到一条消息，告诉您“某些设置由您的组织管理” 。

没有应用程序可以将文件保存在下载文件夹^{(Downloads Folder)}中？

如果您想知道是否可以将其应用于其他程序，那么问题就在这里。应用程序使用User^(User)的相同权限运行。因此，无法控制Microsoft Store之外的任何内容来拒绝或允许访问特定文件夹。但是，如果您无法将任何内容保存到下载文件夹中，则可能是因为对该文件夹的权限访问。以下是如何检查和修复它。

右键单击^{(Right-click)}“下载^(Downloads)”文件夹，然后选择“属性^(Properties)” 。切换到安全^(Security)选项卡，然后选择用户帐户或系统帐户。当您在用户之间切换时，它将显示该User的权限。如果文件夹的写入权限^{( Write permission)}设置为拒绝，则需要将其设为允许。

• 选择User，然后单击Edit按钮
• 在Permissions窗口中，再次选择User，然后取消选中Deny Column下面的Write旁边的框。
• 单击^(Click)应用^(Apply)按钮，然后单击确定按钮。

现在，如果您或任何应用程序写入该文件夹，它应该不会有问题。

我希望这篇文章能够阐明为什么您在将文件写入或保存到“下载”文件夹^{(Downloads folder)}时可能会遇到问题，并且您能够允许或拒绝访问此设备上的“下载”文件夹^(Downloads)

How to Deny or Allow access to Downloads folder on this device

Windows 10 Privacy Settings offer File System settings, which makes sure that unless allowed, Apps will not be able to access the File System, аnd user folders such as Documents, Pictυreѕ, videos, and local OneDrіve Files. Some apps need access to File System to work as intended. In this post, we will show how you can deny or allow access to the Downloads folder.

Deny or Allow access to the Downloads folder on this device

All the users in Windows have access to their personal folders, but applications must request this access, and you can choose to allow or deny the request. When apps get the same permission as their users, it will allow them to manage files and folders inside them.  If you give app permission but change your mind later, then it is possible to turn off the access to File System.

In the earlier version of Windows, there was a dedicated setting for the Downloads folder along with Documents, Pictures, Videos. It has changed, and if you want to deny or allow access to the downloads folder, you will have to manage it through the File System.

To allow or block file system access for a specific app and service

1. Open Windows Settings (Win + I)
2. Navigate to  Privacy > File system.
3. Click on the Change button, and toggle on the File system access for the device.
4. Next, under Allow Apps to access your file system, turn on app access.
5. Lastly, choose which apps can access your file system.

You can choose the individual apps and services for which you want to allow or block file system access and change the settings to On or Off.

To deny file system access for most apps.

Go back to the File System section. To completely turn off the access, Toggle off the global settings, but if you want to turn off individually, you can choose to do it on a per-app basis.

Why some apps and software do not appear in the file system access privacy settings?

Any app which is installed from outside the Microsoft Store will not appear on the list. If you download a program from the internet or install it from USB  or DVD, then it will not be visible here. They are also not affected by the Allow apps access your file system setting.

Note: If you are trying to configure this on a device that is connected with your workaround, you may not be able to manage it. You’ll see a message telling you that “Some settings are managed by your organization” at the top of the File system settings page.

None of the apps can save files in the Downloads Folder?

If you are wondering if the same can be applied to other programs, then here is the problem. Applications run using the same permission of the User. So it will be impossible to control anything outside Microsoft Store to deny or allow access to a specific folder. However, if you are not able to save anything into the downloads folder, it can be because of the permission access to the folder. Here is how to check and fix it.

Right-click on the Downloads folder, and select Properties. Switch to the Security tab, and select the user account or system account. As you switch between the users, it will reveal the permission for that User. If the Write permission to the folder is set to deny, then you need to make it allow.

• Select the User, and then click on Edit button
• In the Permissions window, select the User again, and then uncheck the box next to Write under Deny Column.
• Click on the Apply button, and then click on the Ok button.

Now, if you or any application writes into the folder, it should not have an issue with it.

I hope the post was able to clarify why you may have an issue with writing or saving files into the Downloads folder, and you were able to allow or deny access to the Downloads folder on this device
