Unzip a Bunch of Zips into Their Own Directories

def extract_zip_Files():

    os.chdir(dir_name)  # change directory from working dir to dir with files

    for item in entries:  # loop through items in dir

        if item.endswith(extension):  # check for ".zip" extension

            file_name = os.path.abspath(item)  # get full path of files

            print('file is', file_name)

            zip_ref = zipfile.ZipFile(file_name)  # create zipfile object

            zip_ref.extractall(cwd+"/unZipped/"+item)  # extract file to dir

            zip_ref.close()  # close file

Unzip Multiple Files into Different Directories

Because you specify only one destination path they will all be extracted into c:\users\name\downloads. I suppose the zip archives each contain a folder named "folder", so all contents from all archives end up together in c:\users\name\downloads\folder

You would have to specify a different destination path for each archive. Not sure what your naming convention should be, I have used a simple counter:

$counter = 0
Get-ChildItem 'c:\users\name\downloads' -Filter *.zip | foreach {
    $destination = Join-Path $_.DirectoryName ("YourName" + $counter++)
    Expand-Archive $_.FullName -DestinationPath $destination
}

Of course I suppose, now every of those folders will have the subfolder "folder", but if that's how the archives are built there's not really a way to change that. If you are absolutely sure that all archives have that subfolder, you could do something like this:

$counter = 0
Get-ChildItem 'c:\users\name\downloads' -Filter *.zip | foreach {
    # expand to the root folder first
    Expand-Archive $_.FullName -DestinationPath $_.DirectoryName
    # now rename the extracted "folder" to whatever you like
    Rename-Item (Join-Path $_.DirectoryName "folder") -NewName ("YourName" + $counter++)
}

Script to extract zip files in seperate folders to their own folders

Under unix you could use something like

find <dir> -iname '*.zip' -execdir unzip {} \;

The program find traverses <dir> recursively and on every .zip file it finds it will change to that files directory and executes unzip on it.

From batch file, I Need to recurse directories (and sub directories) and unzip every zip file found into their current directory w/delete of archive

... do (
 ... 7z x ....
 if errorlevel 1 (echo fail %%s) else (echo del %%s)
)

should fix your problem. 7zip appears to follow the rules and return errorlevel as 0 for success and non-zero otherwise. if errorlevel operates on the run-time value of errorlevel.

Unzip multiple zip folders with the original name

As it's unclear upfront what the zip file contains, I suggest to

• first create a folder in D:\Output with the zip files BaseName and unzip there.

## Q:\Test\2019\05\23\SO_56279162.ps1
$ZipFilesPath =  "D:\Input"  # 'A:\Input'  #
$UnzipBase    =  "D:\Output" # 'A:\Output' #

$Shell = New-Object -com Shell.Application

$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)

    $UnzipPath = Join-Path $UnzipBase $ZipFile.BaseName
    New-Item $UnzipPath -ItemType Directory | Out-NUll
    $Location = $Shell.NameSpace($UnzipPath)

    $Location.Copyhere($ZipFolder.items(), 1040)
    $progress++
}

PowerShell extract each zip file to own folder

You could do with a few less variables. When the $zipfiles collection contains FileInfo objects as it appears, most variables can be replaced by using the properties the objects already have.

Also, try to avoid concatenating to a variable with += because that is both time and memory consuming.

Just capture the result of whatever you output in the loop in a variable.

Something like this:

# capture the stuff you want here as array
$info = foreach ($zip in $zipfiles) { 
    # output whatever you need to be collected in $info
    $zip.Name
    # construct the folderpath for the unzipped files
    $dst = Join-Path -Path $zip.DirectoryName -ChildPath $zip.BaseName
    if (!(Test-Path $dst -PathType Container)) {
        $null = New-Item -ItemType Directory $dst -ErrorAction SilentlyContinue
        $null = Expand-Archive -LiteralPath $zip.FullName -DestinationPath $dst -ErrorAction SilentlyContinue
    }
}

# now you can create a multiline string from the $info array
$result = $info -join "`r`n==========`r`n"
