How to Zip a folder skipping some sub folders in powershell.

PowerShell Help
1

Hi,

I have a code like below. In the source folder I have folders, sub folders and files.
I need to zip the entire source folder and place the zip file in to some location, while zipping I need to skip one specific folder. But when am trying with below its not working. I need to have only one zip file without specific folder in that.
Could anyone please suggest a way on this.

$sourcePath = ‘D:\Dinesh\lob1\lata’
$destination = ‘E:\Kumar\lob1\lata\emerged-data-1.zip’
$excludefolder = ‘processarea’

If(Test-Path $destination)
{
Remove-Item -Path $destination -Force -ErrorAction Stop
}

$items = Get-ChildItem -Path $sourcePath -Recurse -Exclude $excludefolder

Add-Type -AssemblyName “system.io.compression.filesystem”

$items | Foreach{
[io.compression.zipfile]::CreateFromDirectory($_.Fullname,$destination)
}

Thanks,
Dinesh

Maybe this, but $excludefolder may have to be the full path, without a slash on the end (and double backslashes in windows for the regex).

$items = Get-ChildItem -Path $sourcePath -Recurse | where fullname -notmatch $excludefolder

Anyone know why “test-path $file -pathtype leaf” doesn’t always work in this case? (I also tried $myfile.) I’m trying “ls -r foo | .\myzip foo.zip”. EDIT: “$file | test-path -pathtype leaf” works every time. EDIT2: I see, the string version of $file wasn’t the full path. Corrected script.

# myzip.ps1                                                                     
# doesn't zip empty folders

Param([parameter(ValueFromPipeline=$True)]$file, 
  [parameter(position=0)]$zipfile)

Begin {
  if (test-path $zipfile) {
    'zipfile exists'
    exit 1
  }

  Add-Type -AssemblyName 'system.io.compression.filesystem'

  # update or create                                                            
  $zip = [System.IO.Compression.ZipFile]::Open($zipfile,'create')
}

Process {                                         
  if ($file | test-path -pathtype leaf) {
    $rel = $file | resolve-path -relative
    $rel = $rel -replace '^\.\\','' # take .\ off front                         
    $rel = $rel -replace '^\./',''  # osx take ./ off front
    # destination, sourcefilename, entryname, compressionlevel                  
    [System.IO.Compression.ZipFileExtensions]::CreateEntryFromFile($zip,
      $rel, $rel, 'optimal')
  } elseif ($file | test-path -pathtype container) {
    "$file is container"
  } else {
    "$file is unknown"
  }
}

End {
  $zip.dispose()
}

I don’t know about you, but I think this script is pretty cool.
