SharePoint Online：使用 PowerShell 筛选列表视图以仅显示子文件夹中的文件

要求：设置列表视图筛选器以显示 SharePoint Online 文档库中特定文件夹中的文件。

如何设置视图过滤器以显示文件夹中的文件？

不幸的是，SharePoint Web 用户界面不允许我们设置基于文件夹或子文件夹的视图过滤器。虽然可以通过编辑 XSLT-CAML 代码来设置列表视图筛选器，以使用 SharePoint Designer 仅显示特定子文件夹中的文件，但以下是我在 SharePoint Online 列表视图上设置筛选器的 PowerShell 方法。

SharePoint Online：PowerShell 创建按文件夹筛选的列表视图

此 PowerShell 脚本创建一个列表视图，显示 SharePoint Online 文档库中特定文件夹中的所有文件和文件夹。

Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
