Powershell script explanation

leadtheway asked
Last Modified: 2016-10-04
I was wondering if someone could help explain what the below powershell script is doing.  It was inherited and whatever its function isn't working correctly, i was hoping to understand a little better to help troubleshoot

$srcDir = "C:\Opex"
$dstDir = "\\tc00afsv02\c$\Shares\zvol2$\OpexTest\Unprocessed"
$bakDir = "C:\OpexBackup"

while ($true){

    $folders = Get-ChildItem -Path $srcDir

    foreach ($folder in $folders){

        $folderPath = $folder.FullName
        $folderName = $folder

        $oxiExists = Test-Path -Path "$folderPath\*.oxi"

        if ($oxiExists){      
            Write-Output "OXI Found in $folderPath"
            $folderExists = Test-Path -Path $dstDir\$folderName
            if (-not $folderExists){

                New-Item -Path $dstDir\$folderName -ItemType Directory -Verbose

                Copy-Item -Path $folderPath -Destination $bakDir -Recurse -Verbose
				Sleep 1
				Copy-Item -Path "$folderPath\*.tif" -Destination $dstDir\$folderName -Recurse -Verbose
				Sleep 1
				Copy-Item -Path "$folderPath\*.oxi" -Destination $dstDir\$folderName -Recurse -Verbose
                Sleep 1
                Remove-Item -Path $folderPath -Recurse -Force -Verbose

        else {
            Write-Output "OXI Not Found"
            Sleep 1

    Sleep 1
