Unzip multiple files via Powershell

Simple and effective.

	[string] $ZipFilesPath = "X:\Somepath\Full\Of\Zipfiles",
	[string] $UnzipPath = "X:\Somepath\to\extract\to"

$Shell = New-Object -com Shell.Application
$Location = $Shell.NameSpace($UnzipPath)

$ZipFiles = Get-Childitem $ZipFilesPath -Recurse -Include *.ZIP

$progress = 1
foreach ($ZipFile in $ZipFiles) {
	Write-Progress -Activity "Unzipping to $($UnzipPath)" -PercentComplete (($progress / ($ZipFiles.Count + 1)) * 100) -CurrentOperation $ZipFile.FullName -Status "File $($Progress) of $($ZipFiles.Count)"
	$ZipFolder = $Shell.NameSpace($ZipFile.fullname)

	$Location.Copyhere($ZipFolder.items(), 1040) # 1040 - No msgboxes to the user - http://msdn.microsoft.com/en-us/library/bb787866%28VS.85%29.aspx

Btw… Watch out… there is a -Recurse on gci… 🙂

ACT filling up your disks?

When you have ACT (The Microsoft Application Compatibility Toolkit) running in your environment you might get disks filled up with XML-files on your ACT-server.

The logprocessor uses those files to populate the database with information. So, when those are processed you do not need them anymore. (If you have a backup of your database…)

So, I did it the easy way, scheduled a powershell command to remove files older than 7 days:

Get-ChildItem D:\ACTLogs -Recurse -Include *.xml* | where {$_.CreationTime -lt (Get-Date).AddDays(-7)} | Remove-Item

If you want a nicer look and feel to your script you can use this instead:

Get-ChildItem D:\ACTLogs -Recurse -Include *.xml* | where {$_.CreationTime -lt (Get-Date).AddDays(-7)} | Sort-Object CreationTime | ForEach-Object {
	Write-Host "Processing: " -ForegroundColor Yellow -NoNewline
	Write-Host $_.FullName -ForegroundColor White -NoNewline
	$span = New-TimeSpan $_.CreationTime $(get-date)
	Write-Host " $($span.Days) days old" -ForegroundColor Yellow -NoNewline

	Remove-Item $_.FullName

	Write-Host " [del]" -ForegroundColor Red
