Waiting for copy process to finish - powershell

Question

Is there any way to wait for the copy process to finish before running another command?
I tried Start-job and Wait-Job, but it doesn't work.
$func = {
function move-tozip
{
param([string]$filedest)
$Shell = New-Object -com Shell.Application
$b = $shell.namespace($zippath.ToString())
$b.CopyHere($filedest.tostring())
#Remove-Item -Path $filedest
}
}
start-job -InitializationScript $func -ScriptBlock {move-tozip $args[0]} -ArgumentList $file

The easiest way to wait for a job to complete is to give it a name and tell Wait-Job to wait on the task with that name, your script will wait for the job with the name WaitForMe to complete and then run the rest of your code once it has.
Using the -Name paramter with your code below:
$func =
{
function Move-ToZip
{
Param([string[]]$path, [string]$zipfile)
if (-not $zipfile.EndsWith('.zip')) {$zipfile += '.zip'}
if (-not (test-path $zipfile))
{
set-content $zipfile ("PK" + [char]5 + [char]6 + ("$([char]0)" * 18))
}
$shell = (new-object -com shell.application).NameSpace($zipfile)
foreach($file in $path)
{
$shell.CopyHere($file)
start-sleep -milliseconds 100
}
}
}
Start-Job -Name "WaitForMe" -InitializationScript $func -ScriptBlock {Move-ToZip -path $args[0] -zipfile $args[1]} -ArgumentList "D:\data.log", "D:\datazip.zip"
Write-Host "Waiting for job to complete"
Wait-Job -Name "WaitForMe"
Write-Host "Job has completed :D"
To zip one file or folder
-ArgumentList "D:\testfile.log", "D:\datazip.zip"
To zip multiple files or folders
-ArgumentList #("D:\testfile.log","D:\testFolder1"), "D:\testzip.zip"

I've adapted code from This MSDN blog to the Move-ToZip function as the previous code didnt work for me at all, i've tested the above code successfully on files and folders. I have not tested the performance of this method, if you wish to compress/zip multiple large files/folders i would highly suggest looking into using a known working library or third party utility like 7zip.
