I have a PowerShell script which should be able to create a zip of a particular folder, which is also in the same location. But the problem is I do not know where this script will be saved. I tried the code below, but I am not able to do it. The Compress-Archieve method shows the argument is null or empty. Please help.
Add-Type -AssemblyName System.IO.Compression.FileSystem
$source = Get-ChildItem -Filter -Directory .\PublishOutput
$dest = Get-Location
$f = "\Kovai.zip"
$final = Join-Path $dest $f
Write-Host $final
[System.IO.Compression.ZipFile]::CreateFromDirectory($source,$final)
$folderToZip = "C:\FolderToZip"
$rootfolder = Split-Path -Path $folderToZip
$zipFile = Join-Path -Path $rootfolder -ChildPath "ZippedFile.zip"
Write-Output "folderToZip = $folderToZip"
Write-Output "rootfolder = $rootfolder"
Write-Output "zipFile = $zipFile"
Compress-Archive -Path $folderToZip -DestinationPath $zipFile -Verbose

Apologies, this question is scattered on the internet but I have yet to find a satisfactory answer that uses only Powershell 2.0 (with .NET v3.5) - no external libraries or programs
I'm using the following code to extract log.txt from ZipFile.zip (no matter log.txt's location)
$Destination = (new-object -com shell.application).NameSpace('C:\ZipExtractDir')
$ZipFile = (new-object -com shell.application).NameSpace('C:\ZipFile.zip')
$Destination.CopyHere(($Zipfile.Items() | where-object {$_.Name -like '*log.txt'}), 1044)
Works if log.txt is in directory root \log.txt
Fails if log.txt is in a subdirectory \Subfolder\log.txt
Fails if referencing the literal (.zip) path
{$_.Name -Like '*Subfolder\log.txt'} (both double & single quotes fail)
Have tried using -eq -like -contains '' "" $_.FullName
I'm quite certain that I'm filtering incorrectly - can anyone help with this code so that it will parse subdirectories as well?
Similar to what you have already done, you can set up the Shell.Application namespaces like this. Then you can copy the extracted directory to the destination path.
$zipFilePath = "Zipfile.zip"
$destinationPath = "C:\Users\Public\Downloads"
$zipfile = (New-Object -Com Shell.Application).NameSpace($zipFilePath)
$destination = (New-Object -Com Shell.Application).NameSpace($destinationPath)
$destination.CopyHere($zipfile.Items())
Then to list the log.txt files, we can contruct the full extracted path with Join-Path. This basically just appends the zip file name from System.IO.Path.GetFileNameWithoutExtension() to the destination path. Then just use Get-ChildItem to list the files recursively with the -Recurse and -Filter switches.
$extractedPath = Join-Path -Path $destinationPath -ChildPath ([System.IO.Path]::GetFileNameWithoutExtension($zipFilePath))
Get-ChildItem -Path $extractedPath -Filter log.txt -Recurse
And to test this for PowerShell 2.0 we can use -version 2 with powershell.exe:
powershell.exe -version 2 .\test.ps1
UPDATE
If you want to inspect files before extracting, you'll need to recurse the directories yourself. Below is a demo of how this can be done.
function New-ZipChildRootFolder
{
param
(
[string]$DestinationPath,
[string]$ZipFileName
)
$folderPath = Split-Path -Path $ZipFileName -Leaf
$destination = (New-Object -ComObject Shell.Application).NameSpace($DestinationPath)
$destination.NewFolder($folderPath)
}
function Get-ZipChildItems
{
param
(
[string]$ZipFilePath,
[string]$DestinationPath
)
$zipfile = (New-Object -ComObject Shell.Application).NameSpace($ZipFilePath)
$zipFileName = [System.IO.Path]::GetFileNameWithoutExtension($ZipFilePath)
Write-Output "Create root zip folder : $zipFileName"
New-ZipChildRootFolder -DestinationPath $DestinationPath -ZipFileName $zipFileName
foreach ($item in $zipFile.items())
{
Get-ZipChildItemsRecurse -Items $item -DestinationPath $DestinationPath -ZipFileName $zipFileName
}
}
function Get-ZipChildItemsRecurse
{
param
(
[object]$Items,
[string]$DestinationPath,
[string]$ZipFileName
)
foreach ($file in $Items.getFolder.Items())
{
if ($file.IsFolder -eq $true)
{
Write-Output "Creating folder : $($file.Path)"
New-ZipChildFolder -Folder $file -DestinationPath $DestinationPath -ZipFileName $ZipFileName
Get-ZipChildItemsRecurse -Items $file -DestinationPath $DestinationPath -ZipFileName $ZipFileName
}
else
{
$filename = Split-Path -Path $file.Path -Leaf
if ($filename -eq "log.txt")
{
Write-Output "Copying file : $($file.Path)"
New-ZipChildFile -File $file -DestinationPath $DestinationPath -ZipFileName $ZipFileName
}
}
}
}
function New-ZipChildFile
{
param
(
[object]$File,
[string]$DestinationPath,
[string]$ZipFileName
)
$destination = New-Object -ComObject Shell.Application
$items = $File.Path.Split("\")
$zipRootIndex = [array]::IndexOf($items, $ZipFileName)
$path = $items[$zipRootIndex..($items.Length - 2)] -join "\"
$fullPath = Join-path -Path $DestinationPath -ChildPath $path
$destination.NameSpace($fullPath).CopyHere($File)
}
function New-ZipChildFolder
{
param
(
[object]$Folder,
[string]$DestinationPath,
[string]$ZipFileName
)
$destination = New-Object -ComObject Shell.Application
$items = $Folder.Path.Split("\")
$zipRootIndex = [array]::IndexOf($items, $ZipFileName)
$folders = $items[$zipRootIndex..($items.Length - 1)]
$currentFolder = $DestinationPath
foreach ($folder in $folders)
{
$destination.NameSpace($currentFolder).NewFolder($folder)
$currentFolder = Join-Path -Path $currentFolder -ChildPath $folder
}
}
Usage:
$zipFilePath = "C:\Zipfile.zip"
$destinationPath = "C:\Users\Public\Downloads"
Get-ZipChildItems -ZipFile $zipFilePath -DestinationPath $destinationPath
I sniped this script online and it works fine for converting the files in the parent folder. It does not however iterate through the child folders. I do not get any errors and I have verified all the folder permissions are correct. Additionally, I have scripts that are coded similar for *.docx and *.pptx files and they run successfully. This one however is not working as expected. Any ideas?
$path = "c:\converted\"
$xlFixedFormat = "Microsoft.Office.Interop.Excel.xlFixedFormatType" -as [type]
$excelFiles = Get-ChildItem -Path $path -include *.xls, *.xlsx -recurse
$objExcel = New-Object -ComObject excel.application
$objExcel.visible = $false
foreach($wb in $excelFiles)
{
$filepath = Join-Path -Path $path -ChildPath ($wb.BaseName + ".pdf")
$workbook = $objExcel.workbooks.open($wb.fullname, 3)
$workbook.Saved = $true
"converted $wb.fullname"
$workbook.ExportAsFixedFormat($xlFixedFormat::xlTypePDF, $filepath)
$objExcel.Workbooks.close()
#get rid of conversion copy
#Remove-Item $wb.fullname
}
$objExcel.Quit()
$excelFiles will contain subfolders, but your construction of $filepath uses only the original $path and current $wb.BaseName without taking into account that the current $wb.FullName may contain a longer path.
Replace
$filepath = Join-Path -Path $path -ChildPath ($wb.BaseName + ".pdf")
with
$filepath = $wb.fullname -replace $wb.extension,".pdf"
Perhaps my question can be a duplicate, but I'm new in powershell, and cannot figure out, what is wrong with my script, that zipping particular directories:
$path = "C:\backup\DEV82"
if(!(Test-Path -Path $path )){
New-Item -ItemType directory -Path $path
}
cd C:\inetpub\wwwroot\dev82\
$SOURCE = Get-ChildItem * -Directory|Where-Object {$_.FullName -match "App_Config|Resources|bin"}
$dtstamp = (Get-Date).ToString("yyyyMMdd_HHmmss")
Add-Type -assembly "system.io.compression.filesystem"
Foreach ($s in $SOURCE)
{
$DESTINATION = Join-path -path $path -ChildPath "$dtstamp.zip"
If(Test-path $DESTINATION) {
Remove-item $DESTINATION
}
[io.compression.zipfile]::CreateFromDirectory($s.fullname, $DESTINATION)
}
If I execute command in $SOURCE variable, it gathers all required directories, which I want zip http://prntscr.com/j0sqri
$DESTINATION also returns valid value
PS C:\> $DESTINATION
C:\backup\DEV82\20180404_223153.zip
but right now only last folder (Resources) exists in zip file.
Ok, I rewrite my script, using, instead of Zipfile class, Compress-Archive with -Update ( -Update allows to add files\folders into existing archive )
$path = "C:\backup\DEV82"
if(!(Test-Path -Path $path )){
New-Item -ItemType directory -Path $path
}
cd C:\inetpub\wwwroot\dev82\
$SOURCE = Get-ChildItem * -Directory|Where-Object {$_.FullName -match "App_Config|Resources|bin"}
$dtstamp = (Get-Date).ToString("yyyyMMdd_HHmmss")
$DESTINATION = Join-path -path $path -ChildPath "$dtstamp.zip"
Add-Type -assembly "system.io.compression.filesystem"
If(Test-path $DESTINATION) {
Remove-item $DESTINATION
}
Foreach ($s in $SOURCE)
{
Compress-Archive -Path $s.fullname -DestinationPath $DESTINATION -Update
}
$SOURCE is already just a list of folder names, so you don't need the FullName property here:
[io.compression.zipfile]::CreateFromDirectory($s.fullname, $DESTINATION)
Either remove it, or remove the Select-Object from the pipeline here:
$SOURCE = Get-ChildItem * -Directory |
Where-Object {$_.FullName -match "App_Config|Resources|bin"} |
Select-Object -ExpandProperty FullName
I have a PowerShell script that moves all files from one location to another that have a date modified older than 3 years. I have it so the file when moved to the new location also keeps the file structure of the original.
I am trying to make it so once the file has been moved to the new location it creates a shortcut in the original directory which points to the new location of the file.
Below is my script so far which does all the above minus the shortcut.
$sourceDir = "C:\Users\bgough\Documents\powershell\docs"
$archiveTarget = "C:\Users\bgough\Documents\archive"
$dateToday = Get-Date
$date = $dateToday.AddYears(-3)
$items = Get-ChildItem $sourceDir -Recurse |
Where-Object {!$_.PSIsContainer -and $_.LastWriteTime -le $date}
foreach ($item in $items)
{
$withoutRoot = $item.FullName.Substring([System.IO.Path]::GetPathRoot($item.FullName).Length);
$destination = Join-Path -Path $archiveTarget -ChildPath $withoutRoot
$dir = Split-Path $destination
if (!(Test-Path $dir))
{
mkdir $dir
}
Move-Item -Path $item.FullName -Destination $destination
$WshShell = New-Object -ComObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut("$sourceDir")
$Shortcut.TargetPath = $destination
$Shortcut.Save()
}
In my script I have included my attempt at creating this shortcut but it hasn't helped. I have also read through the following but don't understand it too well..
How to create a shortcut using Powershell
Powershell Hard and Soft Links
Edit:
I have successfully got the shortcut to create and in the original folder. However, I can't seem to figure out how to pass a variable to use as the shortcut name. At the moment a string is hard coded, which is what the shortcut gets named. Please see code below: I would like to set the name as the item full name (Same name as document that was moved).
$sourceDir = "C:\Users\bgough\Documents\powershell\docs"
$archiveTarget = "C:\Users\bgough\Documents\archive"
$dateToday = Get-Date
$date = $dateToday.AddYears(-3)
$items = Get-ChildItem $sourceDir -recurse | Where-Object {!$_.PsIsContainer -and $_.LastWriteTime -le $date}
foreach ($item in $items)
{
$withoutRoot = $item.FullName.Substring([System.IO.Path]::GetPathRoot($item.FullName).Length);
$destination = Join-Path -Path $archiveTarget -ChildPath $withoutRoot
$dir = Split-Path $destination
if (!(Test-Path $dir))
{
mkdir $dir
}
Move-Item -Path $item.FullName -Destination $destination
$wshshell = New-Object -ComObject WScript.Shell
$desktop = [System.Environment]::GetFolderPath('Desktop')
$lnk = $wshshell.CreateShortcut($sourceDir + "\ShortcutName.lnk")
$lnk.TargetPath = "$destination"
$lnk.Save()
}
.lnk files are fine when you're using Explorer but they don't play well in Powershell or a command prompt.
What you need to do is create a symbolic link for the file. You can't do this in Powershell, but there is a command line utility called mklink that does it. I've wrapped it in a function so that you can call it:
function CreateLink
{
param
(
[string] $LinkName,
[string] $TargetFile
)
&"cmd.exe" /c mklink "$LinkName" "$TargetFile" | Out-Null
}
In your example you would call it like this:
CreateLink -LinkName $item.FullName -TargetFile $destination
When you look at the directory in Powershell the file will show up as being 0 bytes in size. Don't worry about that.
Thanks for your script Android Magic.
I have modified it to:
Copy a set of files from source to destination
It creates the identical folder structure on the destination, even if the folders are empty
It then creates a symbolic link to the archived file. SymbolicLink support was added in Powershell v5.1. You have to run the script as Admin in order for the Symbolic Link creation to work.
I'd like to add a function to email if anything goes wrong and a summary of status, but that's for another day.
$sourceDir = "\\Fileserver1\IT\Vendor"
$archiveTarget = "\\FS-ARCHIVE\Archive\Fileserver1\IT\Vendor"
$rootArchivePath = "\\FS-ARCHIVE\Archive"
$dateToday = Get-Date
$date = $dateToday.AddYears(-3)
# Copy folder structure to Archive
Get-ChildItem -Path $sourceDir -Recurse |
?{ $_.PSIsContainer } |
Copy-Item -Destination {Join-Path $archiveTarget $_.Parent.FullName.Substring($sourceDir.length)} -Force
$items = Get-ChildItem $sourceDir -Recurse -Attributes !Directory |
Where-Object {$_.LastAccessTime -le $date}
foreach ($item in $items)
{
$withoutRoot = Split-Path -Path $item.FullName
$destination = $rootArchivePath + $withoutRoot.Remove(0,1)
$destFile = $destination + "\" + $item
Move-Item -Force -Path $item.FullName -Destination $destination -Verbose
New-Item -ItemType SymbolicLink -Path $withoutRoot -Name $item -Value $destFile -Force -Verbose
}
I need to unzip a specific directory from a zipfile.
Like for example extract the directory 'test\etc\script' from zipfile 'c:\tmp\test.zip' and place it in c:\tmp\output\test\etc\script.
The code below works but has two quirks:
I need to recursively find the directory ('script') in the zip file (function finditem) although I already know the path ('c:\tmp\test.zip\test\etc\script')
With CopyHere I need to determine the targetdirectory, specifically the 'test\etc' part manually
Any better solutions? Thanks.
The code:
function finditem($items, $itemname)
{
foreach($item In $items)
{
if ($item.GetFolder -ne $Null)
{
finditem $item.GetFolder.items() $itemname
}
if ($item.name -Like $itemname)
{
return $item
}
}
}
$source = 'c:\tmp\test.zip'
$target = 'c:\tmp\output'
$shell = new-object -com shell.application
# find script folder e.g. c:\tmp\test.zip\test\etc\script
$item = finditem $shell.NameSpace($source).Items() "script"
# output folder is c:\tmp\output\test\etc
$targetfolder = Join-Path $target ((split-path $item.path -Parent) -replace '^.*zip')
New-Item $targetfolder -ItemType directory -ErrorAction Ignore
# unzip c:\tmp\test.zip\test\etc\script to c:\tmp\output\test\etc
$shell.NameSpace($targetfolder).CopyHere($item)
I don't know about most elegant, but with .Net 4.5 installed you could use the ZipFile class from the System.IO.Compression namespace:
[Reflection.Assembly]::LoadWithPartialName('System.IO.Compression.FileSystem') | Out-Null
$zipfile = 'C:\path\to\your.zip'
$folder = 'folder\inside\zipfile'
$dst = 'C:\output\folder'
[IO.Compression.ZipFile]::OpenRead($zipfile).Entries | ? {
$_.FullName -like "$($folder -replace '\\','/')/*"
} | % {
$file = Join-Path $dst $_.FullName
$parent = Split-Path -Parent $file
if (-not (Test-Path -LiteralPath $parent)) {
New-Item -Path $parent -Type Directory | Out-Null
}
[IO.Compression.ZipFileExtensions]::ExtractToFile($_, $file, $true)
}
The 3rd parameter of ExtractToFile() can be omitted. If present it defines whether existing files will be overwritten or not.
As far as the folder location in a zip is known, the original code can be simplified:
$source = 'c:\tmp\test.zip' # zip file
$target = 'c:\tmp\output' # target root
$folder = 'test\etc\script' # path in the zip
$shell = New-Object -ComObject Shell.Application
# find script folder e.g. c:\tmp\test.zip\test\etc\script
$item = $shell.NameSpace("$source\$folder")
# actual destination directory
$path = Split-Path (Join-Path $target $folder)
if (!(Test-Path $path)) {$null = mkdir $path}
# unzip c:\tmp\test.zip\test\etc\script to c:\tmp\output\test\etc\script
$shell.NameSpace($path).CopyHere($item)
Windows PowerShell 5.0 (included in Windows 10) natively supports extracting ZIP files using Expand-Archive cmdlet:
Expand-Archive -Path Draft.Zip -DestinationPath C:\Reference
