我知道很多已經使用Powershell壓縮文件的內容,但是我找不到一個完全符合我需要的方法。Powershell Zip文件夾內容

我希望能夠壓縮文件夾和文件爲.zip文件夾,而無需Zip文件裏的父文件夾。因此,例如,我有一個名爲STUFF的文件夾,其中包含文件/文件夾,我想將其壓縮到名爲STUFF.zip的文件夾中。然後,該文件夾的結構將是STUFF.zip>文件/文件夾不STUFF.zip> STUFF>文件/文件夾,因爲我目前得到使用此代碼...

function CountZipItems(
[__ComObject] $zipFile) 
{ 
If ($zipFile -eq $null) 
{ 
    Throw "Value cannot be null: zipFile" 
} 

Write-Host ("Counting items in zip file (" + $zipFile.Self.Path + ")...")

使用

Remove-Item "H:\STUFF.zip" 

[IO.DirectoryInfo] $directory = Get-Item "H:\STUFF" 
ZipFolder $directory 

完全學分制對此代碼使用here。我非常感謝任何幫助,這項功能對我的項目至關重要!不幸的是,我不能使用社區擴展模塊,因爲其他PC上運行的這個模塊沒有安裝這個模塊。

謝謝!

Dotnet 4.5增加了zip功能,應該給你比COM方法更好的選擇。其他電腦有嗎? – mjolinor

如果使用PSCX Module您將使用下面的代碼行,以獲得您所需要的:

write-zip h:\Stuff\* myzipfile.zip 
14

按照@mjolinor「H:\東西\」,如果你有.NET 4.5安裝,您可以運行以下內容:

$src = "H:\Stuff\" 
$dst = "H:\Stuff.zip" 
[Reflection.Assembly]::LoadWithPartialName("System.IO.Compression.FileSystem") 
[System.IO.Compression.ZipFile]::CreateFromDirectory($src, $dst)

新的解決方案可提供WMF 5(遠的不說新^^)

Compress-Archive -Path H:\stuff\* -DestinationPath H:\stuff.zip -Force
