我正在使用 PowerShell 将多个 大 文件上传到 SharePoint 库子文件夹。
使用下面的链接/代码，我只能将文件上传到根目录，但不能上传到子文件夹。
如何将其上传到库子文件夹？其他一切正常。

您正在使用代码将文件添加到文档库的根文件夹：$Docs.RootFolder.Files.Add($FileCreationInfo)
要将文件添加到子文件夹，您需要先获取该子文件夹：
$folder = $web.GetFolderByServerRelativeUrl($folderUrl)
$ctx.Load($folder)
$ctx.ExecuteQuery()
那么你可以像现在一样添加文件
$folder.Files.Add($FileCreationInfo)

供您参考的示例测试脚本。

李给你的东西在正确的轨道上，杰克。有几件事你可以做，但你想改变。
首先 - 由于您使用的是相对 URL，请将其作为参数添加到函数中。这是您的文档库名称之后的 URL 部分（即 /sub-folder/sub-folder）：
Function UploadFileInSlice ($ctx, $libraryName, $fileName, $FolderRelativeURL)
然后 - 创建一个变量来构建您的目标 URL（记得替换空格，并删除逗号：
$targetURL = "/sites/dev/$($libraryName.Replace(',','').Replace(' ','%20'))$($FolderRelativeURL.Replace(' ','%20'))"
下一步 - 由于您使用的是相对 URL，因此无需加载根文件夹。您仍然可以使用其相对 URL 上传到它。但是，您将希望您的上下文在以后知道目标文件夹。所以在函数开始之前，你只需要这 4 行来设置你的上下文：
$web = $ctx.web
$folder = $web.GetFolderByServerRelativeUrl($targetURL)
$ctx.Load($folder)
$ctx.ExecuteQuery()
Lee 在“常规方法”中提供的位适用于小于块大小的文件，但在大文件部分，您希望使用该 $upload 对象。您需要该对象才能让其余代码上传切片。与您的原始来源和 Lee 的回答相比，这应该看起来很熟悉：
$Upload = $folder.Files.Add($fileInfo)
最后 - 在第一个切片（空文件）上传后，您需要更改 $upload 对象的引用。原始代码仍在查看文件的根目录。您必须将其定向到您的相对 URL。由于您之前已将文件夹加载到上下文中，因此您可以检索所需的属性（在本例中，您将获得其 ServerRelativeUrl）：
$Upload = $ctx.Web.GetFileByServerRelativeUrl($folder.ServerRelativeUrl + [System.IO.Path]::AltDirectorySeparatorChar + $UniqueFileName);
我有构建 2 个不同 URL 的脚本的原因是因为 $web.GetFolderByServerRelativeUrl 想要一个 Web URL（这意味着 %20 而不是空格并且没有逗号），而 $ctx.Web.GetFileByServerRelativeUrl 想要一个直接 URL（它可以有空格；它不喜欢带有 %20 的 URL）。您可能没有这个问题，并且可以跳过其中的一些代码。然而，我的用户对我并不友善，并且尽可能使用空格。
最后一点，您可能希望在“常规方法”部分的“返回”之前添加 $Filestream.dispose()。没有它，该文件将被锁定，直到脚本结束，如果需要，您以后无法访问/修改它。
我希望这对您有所帮助。我也不得不在互联网上搜索如何将大文件上传到子目录中。
