Term is not recognized when executing PowerShell Script through SQL Agent using CMDEXEC

Question

I am trying to simply execute a PowerShell script that is stored in a file on a network drive through SQL Agent as a job. The script is a basic copy from one directory to another.  I have run and successfully executed this from a command prompt outside
of SQL Agent.  When I execute this through SQL Agent as a Operating System (CmdExec) command I am getting an error that the term is not recognized as the name of a cmdleet, function, script file or operable program. I have executed many different ways
put found an article to use double quotes in the network path which I have done with no success. 
I am executing the following command as a job in SQL Agent:
PowerShell H:\"\PowerShell""\PS_Scripts\"\batchcopyFFLWithProgress.ps1 through SQL Agent job
I get the following error message:
 04/21/2015 10:01:09,Copy FFL Files,Error,1,NY11266-LTW7E\JPLAPTOPSQL,Copy FFL Files,Copy FFL files,,Executed as user: NT Service\SQLAgent$JPLAPTOPSQL. H:\PowerShell\PS_Scripts\batchcopyFFLWithProgress.ps1 : The term   'H:\PowerShell\PS_Scripts\batchcopyFFLWithProgress.ps1'
is not recognized as   the name of a cmdlet<c/> function<c/> script file<c/> or operable program. Check the   spelling of the name<c/> or if a path was included<c/> verify that the path is   correct and try again.

Content of batchcopyFFLWithProgress.ps1 which has the PowerShell script:
$source=ls H:\SQLTest\Script\TestData\*.*
$i=1
$source| %{
    [int]$percent = $i / $source.count * 100
    Write-Progress -Activity "Copying ... ($percent %)" -status $_ -PercentComplete $percent -verbose
    copy $_.fullName -Destination H:\test -Recurse
    $i++
I have searched the internet and have not found any resolution to my error.  If someone has experienced this error and found the resolution I would greatly appreciate your help.

I have change the service account for SQL Agent to be my domain account as I have local admin rights to my laptop.  I stopped and started the services for SQL Agent and than started the job to run which is copying locally to minimize any network drive
issues.  I am still getting the same error message as it is showing that I am executing the job under my domain account?  Any thoughts what it could be?
