Trying to delete all files in all subfolders with a Powershell script, but can't find a way to exclude the deletion of files in the root folder
问题
我写了一个PowerShell脚本，用于删除当前路径的子文件夹中的所有文件。它能正常工作，但也会删除当前/根文件夹中的所有文件。如何排除该文件夹？
$CountedFiles = (Get-ChildItem -File -Recurse | Measure-Object).Count
$NewCountedFiles = ($CountedFiles - 1)
$path = Get-Location
Get-ChildItem -Path $path -Include *.* -Exclude *.ps1 -File -Recurse | foreach { $_.Delete()}
Write-Host "已删除 $NewCountedFiles 个文件，包括所有子文件夹和当前文件夹，路径为: $path"
pause
目前，我已经排除了.ps1（PowerShell脚本文件）以进行测试，以防它删除自身。
我尝试找到一种排除根文件夹的方法，但由于我是PowerShell的新手，还没有找到。希望有人知道一个简单的方法来实现。
英文:
I wrote a Powershell script that deletes all files in the subfolders of the current path.
It works fine, but it also deletes all files in the current/root folder. How can I exclude that folder?
$CountedFiles = (Get-ChildItem -File -Recurse | Measure-Object).Count
$NewCountedFiles = ($CountedFiles - 1)
$path = Get-Location
Get-ChildItem -Path $path -Include *.* -Exclude *.ps1 -File -Recurse | foreach { $_.Delete()}
Write-Host "Es wurde(n) '$NewCountedFiles' Datei(en) in allen Unterordnern und im derzeitigen Ordner im Pfad: '$path' gelöscht!"
pause
Currently I have it so that it exludes the .ps1 (Powershell Script File) for testing so it doesn't deletes itself.
I tried to find a way to exclude the root folder, but haven't found one since I am new to Powershell. I hope that someone knows an easy why to do so.

如果您需要删除文件，但不删除子文件夹，您可以尝试以下操作：
$files = Get-ChildItem -Path $pwd -File -Recurse
$filesToDelete = $files | Where-Object { $_.Directory.FullName -ne $pwd }
$filesToDelete | Remove-Item -Force
这样可以删除所有文件，而不会删除根目录内容和子文件夹。
英文:
If you need to delete the files, but not the subfolders, you can try this:
$files = Get-ChildItem -Path $pwd -File -Recurse
$filesToDelete = $files | Where-Object { $_.Directory.FullName -ne $pwd }
$filesToDelete | Remove-Item -Force
And you delete all the files without remove the root content and the subfolders.

你可以只迭代当前位置的顶级子目录子项，而不是从当前位置本身开始：
Get-ChildItem -Directory | ForEach {
Get-ChildItem -Recurse $_ | Sort-Object -Property FullName | ForEach {
$_.Delete()
}
}
这将删除子目录和文件；如果你只想删除文件，请使用Victor Silva的答案。
英文:
You could just iterate over the top-level subdirectory children of the current location instead of starting at the current location itself:
Get-ChildItem -Directory | ForEach {
Get-ChildItem -Recurse $_ | Sort-Object -Property FullName | ForEach {
$_.Delete()
}
}
That will delete subdirectories as well as files; if you only want to delete the files, go with Victor Silva's answer.

以下是您要翻译的内容：
# 以下是 PowerShell 习惯用法的解决方案，利用了 [`Get-ChildItem`](https://learn.microsoft.com/en-us/powershell/module/Microsoft.PowerShell.Management/Get-ChildItem) 和 [`Remove-Item`](https://learn.microsoft.com/en-us/powershell/module/Microsoft.PowerShell.Management/Remove-Item) 中的直接管道支持：
Get-ChildItem $path -Directory | # 仅获取子目录
Get-ChildItem -Include *.* -Exclude *.ps1 -File -Recurse | # 在每个目录中查找文件
Remove-Item -WhatIf
# 注意：上述命令中的 [`-WhatIf` 通用参数](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_commonparameters#-whatif) 用于 _预览_ 操作。在确保操作会执行所需操作后，删除 `-WhatIf` 并重新执行命令。
# 如果在第二个 `Get-ChildItem` 调用中添加 [`-OutVariable`](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_CommonParameters#-outvariable)` files`，您可以使用 `$files.Count` 来获取稍后删除的文件数。
英文:
<!-- language-all: sh -->
A PowerShell-idiomatic solution that takes advantage of direct pipeline support in Get-ChildItem and Remove-Item:
Get-ChildItem $path -Directory | # Get only the subdirectires
Get-ChildItem -Include *.* -Exclude *.ps1 -File -Recurse | # Look for files in each
Remove-Item -WhatIf
<sup>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.</sup>
If you add -OutVariable files to the 2nd Get-ChildItem call, you can use $files.Count to get the count of deleted files later.
