[英]PowerShell: Extract specific files/folders from a zipped archive
Say foo.zip
contains: 说
foo.zip
包含:
a
b
c
|- c1.exe
|- c2.dll
|- c3.dll
where a, b, c
are folders. 其中
a, b, c
是文件夹。
If I 如果我
Expand-Archive .\foo.zip -DestinationPath foo
all files/folders in foo.zip
are extracted. 提取
foo.zip
中的所有文件/文件夹。
I would like to extract only the c
folder. 我想只提取
c
文件夹。
try this 试试这个
Add-Type -Assembly System.IO.Compression.FileSystem
#extract list entries for dir myzipdir/c/ into myzipdir.zip
$zip = [IO.Compression.ZipFile]::OpenRead("c:\temp\myzipdir.zip")
$entries=$zip.Entries | where {$_.FullName -like 'myzipdir/c/*' -and $_.FullName -ne 'myzipdir/c/'}
#create dir for result of extraction
New-Item -ItemType Directory -Path "c:\temp\c" -Force
#extraction
$entries | foreach {[IO.Compression.ZipFileExtensions]::ExtractToFile( $_, "c:\temp\c\" + $_.Name) }
#free object
$zip.Dispose()
This one does not use external libraries: 这个不使用外部库:
$shell= New-Object -Com Shell.Application
$shell.NameSpace("$(resolve-path foo.zip)").Items() | where Name -eq "c" | ? {
$shell.NameSpace("$PWD").copyhere($_) }
Perhaps it can be simplified a bit. 也许它可以简化一点。
Here is something that works for me. 这是适合我的东西。 Of Course, you will need to edit the code to fit your objective
当然,您需要编辑代码以适合您的目标
$results =@()
foreach ($p in $Path)
{
$shell = new-object -Comobject shell.application
$fileName = $p
$zip = $shell.namespace("$filename")
$Results += $zip.items()| where-object { $_.Name -like "*C*" -or $_.Name -like
"*b*" }
}
foreach($item in $Results )
{
$shell.namespace($dest).copyhere($item)
}
