英文:

Delete Files under certain Folders and Leave Folders Intact with Powershell

问题 {#heading}

以下是翻译好的部分：

我正在尝试清理文件夹，保留文件夹，但删除文件。但我不想删除某些文件夹中的任何内容，但我无法弄清楚如何操作。到目前为止，我有以下代码，但它会删除每个文件夹中的所有内容，并且还会删除第一级上的两个脚本。我已经用红色矩形标记的那些我需要脚本忽略，其他文件夹我希望从中删除文件。

Get-ChildItem -Path 'C:\Users\Tara.verity\Documents_Local\RemoveFilesFromFolders' -Exclude "*.exe","*.config","assets", "Documentation" -Recurse | ForEach-Object {$_.Delete()}

英文:

I am trying to clean up folders, keeping the folders, but removing the files. I do not want to delete anything in some folders though and cannot figure out how. Here is what I have so far, but it deletes everything in each folder and also removes the 2 scripts on the first level. The ones I have marked with a red rectangle I need the script to ignore, the other folders I want the files deleted from.

Get-ChildItem -Path 'C:\Users\Tara.verity\Documents_Local\RemoveFilesFromFolders'  -Exclude "*.exe","*.config","assets", "Documentation" -Recurse | ForEach-Object {$_.Delete()}

从Get-ChildItem调用中移除-Recurse，将结果传递给另一个Get-ChildItem调用，以确保在目标文件夹中的项目中包括子目录的项目被列举（但不包括在输出中），并将结果传递给Remove-Item：

Get-ChildItem `
    -Path 'C:\Users\Tara.verity\Documents_Local\RemoveFilesFromFolders' `
    -Exclude *.exe, *.config, assets, Documentation |
  Get-ChildItem -Force |
  Remove-Item -Recurse -WhatIf

注意：

• 即使您的输入路径是字面路径，因此通常应通过-LiteralPath传递，但Windows PowerShell中的一个错误（在PowerShell（Core）中已修复）会导致在与-LiteralPath结合使用时忽略-Include和-Exclude

  • 如果您使用-Include而不是-Exclude，您还必须确保-Path值以\*结尾（或只是*），原因请参见此答案。

• 请注意，通过第二个Get-ChildItem调用的枚举包括任何嵌套的子目录，这些子目录也会被Remove-Item删除（-Recurse开关会防止出现确认提示）。

  • 如果您只想从这些目录中删除文件，请在第二个Get-ChildItem调用中添加-File。

  • 如果您想递归地从这些目录中删除所有文件，同时保留嵌套的子目录，请添加-File -Recurse。

英文:

<!-- language-all: sh -->

Remove -Recurse from the Get-ChildItem call, pipe the results to another Get-ChildItem call to ensure that subdirectories among the item in the target folders have their items enumerated (without being included in the output themselves), and pipe the results to Remove-Item:

Get-ChildItem `
    -Path 'C:\Users\Tara.verity\Documents_Local\RemoveFilesFromFolders' `
    -Exclude *.exe, *.config, assets, Documentation |
  Get-ChildItem -Force |
  Remove-Item -Recurse -WhatIf

^{Note: The -WhatIf common parameter in the command above previews the operation. Remove -WhatIf and re-execute once you're sure the operation will do what you want.}

Note:

• Even though your input path is a literal path and should therefore normally be passed via -LiteralPath, a bug in Windows PowerShell (since fixed in PowerShell (Core)) causes -Include and -Exclude to be ignored when combined with -LiteralPath

  • If you were to use -Include rather than -Exclude you'd have to additionally ensure that your -Path value ends in \* (or is just *), for the reasons explained in this answer.

• Note that the enumeration via the second Get-ChildItem call includes any nested subdirectories, which are also removed by Remove-Item(the -Recurse switch prevents a confirmation prompt).

  • If you only want to remove the files from these directories, add -File to the second Get-ChildItem call.

  • If you want to remove all files from these directories recursively while retaining nested subdirectories , add -File -Recurse.
