Question

我正在尝试使用Powershell创建网络目录中特定文件夹中所有* .xml文件的存档（不包括子目录中可能已存在的任何.zip文件）。我需要循环遍历所有子目录，并且仅压缩存在的文件，并且只有* .xml文件应该包含在子目录中的zip中 - zip需要具有子目录和名称中的日期。我还希望在压缩后从子目录中删除任何xml文件。

以下是我目前的情况：

[Reflection.Assembly]::LoadWithPartialName( "System.IO.Compression" )
[Reflection.Assembly]::LoadWithPartialName( "System.IO.Compression.FileSystem" )

$directory = 'C:\some directory' 

$folderstozip = Get-ChildItem $directory -Recurse -Filter *.xml -Exclude *.zip |
    Select-Object -ExpandProperty DirectoryName -Unique

foreach ($folder in $folderstozip) { 
    $archive = $folder + ((Get-Date).ToString(' yyyy-MM-dd')) + '.zip'

    If(Test-Path $archive) { Remove-Item $archive }

    [System.IO.Compression.ZipFile]::CreateFromDirectory($folder, $archive, 'Optimal', $false)
}

这是在上面的目录中创建zip文件，而不是在xml文件所在的子目录中。我也无法弄清楚如何正确使用Remove-Item cmdlet。 Remove-Item $folderstozip -Recurse -Filter *.xml删除整个目录，我只想删除xml文件。它还包括zip中子目录中存在的任何zip文件。

有人能帮助吗？任何帮助都感激不尽！如果有任何不清楚的地方，如果您需要进一步的信息，请告诉我。

谢谢你，亲切的问候， LR

Answer 1

就Remove-Item而言，如果您只想删除某个扩展名的文件，请尝试使用-Include开关而不是-Filter。此外，您的文件夹路径后面需要\*表示您正在查看文件夹的内容而不是文件夹本身。我会改变你提到的那一行

Remove-Item $folderstozip\* -Recurse -Include *.xml

Answer 2

在可行的选择之后移动拉链吗？

Move-Item -Path "$directory\$archive" -Destination $folder

或者，我认为问题在于这一行：

$archive = $folder + ((Get-Date).ToString(' yyyy-MM-dd')) + '.zip'

打印出来以确保它包含您的想法。本来以为它需要像：

$archive = $folder.FullName + "\" ((Get-Date).ToString(' yyyy-MM-dd')) + '.zip'

Just to put it out there, this is what I ended up with.
It does exactly what I need, excludes already zipped files from the new zips, writes details of the successful zips to a log file and also reads a list of directories to search through and zip from a text file.

Hopefully someone will find this useful :) It may not be as streamlined as a Powershell expert would code it, but i'm pretty happy with it!

Thanks!
