I need help fixing this powershell Unzip and copy script

I’m getting an error message when I run this script.

It does copy the file to the target location.

I will be a scheduled task so I just want to C:\Source$subfolder because it will recurse.

The folder nested will be 20180111 or 20180112

This is the error that I’m getting

xtract: C:\Target\New\20180108/D2_August_27_2017-workspace.xml
New-Object : Exception calling “.ctor” with “2” argument(s): “The directory name is invalid.”

I left out the part of the script with the email details.

This is the original script before modification:

	$message.Subject = "$foldername folder recived ";
	$message.Body = "$FileNames files are received in the source folder";
}else {
	$message.Subject = "$foldername folder copied";
	$message.Body = "$FileNames files are copied in the target folder";

Unzip “$srcZipFile” “$sourceFolder$zipFolderName”
$tempList = get-childitem “$sourceFolder$zipFolderName” -recurse
$zipFileList = $tempList | where {($.extension -eq “.err”) -or ($.extension -eq “.out”) }

	if ($zipFileList.length -gt 0 ){

Write-Host “There is no files received today yet”

Cohen, this appears to be the same question your asked here-
Are you saying that what was provide there did not get you to your resolution?

Is it really that hard to use the code formatting tags? You would do yourself and us a favor using them. I’d be easier to read and to debug your badly formatted scripts.
If I can see right you’re trying to pipe Out-Null to New-Object. What should be the purpose of that construct?

I was able to get it fixed.

I used this script instead. It works, but the things I want to do is to only look for the latest folder. The client is sending folder in yyyymmdd Where do I need to add this to the script. I want to add a line on the only scan for the most reached created folder. It scans all the other subfolders and transfers all the files.

The script work, but it is scanning all the folder in the source path.
