使用Powershell脚本压缩文件夹

Question

写下面的代码将文件移动到驱动器上的特定Year-Month文件夹。不过，我还想在操作结束时压缩我写入的文件夹。我怎么做？

# Get the files which should be moved, without folders 
$files = Get-ChildItem 'D:\NTPolling\InBound\Archive' -Recurse | where {!$_.PsIsContainer} 

# List Files which will be moved 
# $files 

# Target Filder where files should be moved to. The script will automatically create a folder for the year and month. 
$targetPath = 'D:\SalesXMLBackup' 

foreach ($file in $files) 
{ 
# Get year and Month of the file 
# I used LastWriteTime since this are synced files and the creation day will be the date when it was synced 
$year = $file.LastWriteTime.Year.ToString() 
$month = $file.LastWriteTime.Month.ToString() 

# Out FileName, year and month 
$file.Name 
$year 
$month 

# Set Directory Path 
$Directory = $targetPath + "\" + $year + "\" + $month 
# Create directory if it doesn't exsist 
if (!(Test-Path $Directory)) 
{ 
New-Item $directory -type directory 
} 

# Move File to new location 
$file | Move-Item -Destination $Directory 
} 

的意图是将这些文件移动到一个文件夹，压缩它们并存档以备后用。所以我会每月安排一次运行前一个月

如果您使用PowerShell的V5，那么你可以使用Compress-Archive功能：

Get-ChildItem $targetPath | Compress-Archive -DestinationPath "$targetPath.zip" 

这将压缩D:\SalesXMLBackup到D:\SalesXMLBackup.zip

这是我用来解压缩目录中所有文件的代码。你只需要修改它足以压缩而不是解压缩。

$ZipReNameExtract = Start-Job { 
#Ingoring the directories that a search is not require to check 
$ignore = @("Tests\","Old_Tests\") 

#Don't include "\" at the end of $loc - it will stop the script from matching first-level subfolders 
$Files=gci $NewSource -Fecurse | Where {$_.Extension -Match "zip" -And $_.FullName -Notlike $Ignore} 
    Foreach ($File in $Files) { 
     $NewSource = $File.FullName 
     #Join-Path is a standard Powershell cmdLet 
     $Destination = Join-Path (Split-Path -parent $File.FullName) $File.BaseName 
     Write-Host -Fore Green $Destination 
     #Start-Process needs the path to the exe and then the arguments passed seperately. 
     Start-Process -FilePath "C:\Program Files\7-Zip\7z.exe" -ArgumentList "x -y -o $NewSource $Destination" -Wait 
    } 
} 
Wait-Job $ZipReNameExtract 
Receive-Job $ZipReNameExtract 

让我知道它是否有帮助。
