Powershell v4: Start-Process rar.exe

Question

Good day.
I apologize in advance for my bad english.
I need to call rar.exe (cmd winrar) with Start-Process cmdlet (and not with &), because I need the script waits for completion of archiving, so I want to use it with -Wait parameter. But I do not really know how to type Argumentlist:
Start-Process -FilePath "path_to_winrar\rar.exe" -ArgumentList "a -df $ArchiveName @$filelist" -Wait
Where $filelist is the list with files to archive.
Actually i have tried many combinations but did not succeed, the archive just does not created.
Please help.

I don`t know how to explain this. It works if I define variables in script, for example easy script to collect files, put them to the list, archive them and then delete (it is just an example, I know I can delete files by
-df parameter of rar.exe):
#get some files for archiving
$Files = Get-ChildItem "E:\Startx" -Recurse -File
#define list of files for archiving
$filelist = "G:\Utilization\Reports\filelist.txt"
#add files fullnames to the list
$Files | foreach {$_.Fullname} | Out-File $filelist -Append
$reportname = "G:\Utilization\Reports\Del_report.txt"
$archivename = "G:\Utilization\Archives\archive.rar"
#add files from $filelist to archive
if ($Files -ne $null) {&"C:\Users\kopilov\Desktop\WinRar\rar.exe" a $Archivename "@$filelist"}
#then delete all these files
foreach ($file in $Files)
if ($file -ne $null)
"Deleting $($file.Fullname)" | Out-File $ReportName -Append
Remove-Item $file.Fullname | Out-Null
else
"No files for deletion" | Out-File $ReportName -Append
BUT there is another example, where files collected by lastaccesstime attribute (actually it does not matter),
however variables are set as parameters during start of the script:
C:\Users\kopilov\Desktop\arraytest.ps1 -TargetFolder "E:\Startx" -Minutes 1
And the file deletion function does not wait for the rar.exe to complete, and files are deleted
before archiving.
The script itself:
param(
[parameter(Mandatory = $true)]
$TargetFolder,
[parameter(Mandatory = $true)]
$Minutes
$Now = Get-Date
$LastAccess = $Now.AddMinutes(-$Minutes)
$Files = Get-ChildItem $TargetFolder -Recurse -File | Where {$_.LastAccessTime -le "$LastAccess"}
$NameDate = (Get-Date).tostring("dd.MM.yyyy")
$ReportName = 'G:\Utilization\Reports\' + "$((Get-Item $TargetFolder).name)_" + $NameDate + '.txt'
$ArchiveName = 'G:\Utilization\Archives\' + "$((Get-Item $TargetFolder).name)_" + $NameDate + '.zip'
$filelist = 'G:\Utilization\Reports\'+ "$((Get-Item $TargetFolder).name)list_" + $NameDate + '.txt'
$Files | foreach {$_.Fullname} | Out-File $filelist -Append
if ($Files -ne $null) {&"C:\Users\kopilov\Desktop\WinRar\rar.exe" a $ArchiveName "@$filelist"}
foreach ($file in $Files)
if ($file -ne $null)
"Deleting $($file.Fullname)" | Out-File $ReportName -Append
Remove-Item $file.Fullname | Out-Null
else
"No files to delete" | Out-File $ReportName -Append
It is almost the same, but call operator & works different. Do not know how to explain this.
P.S. i just figured out that Start-Process with -Wait parameter works like call operator &.
Sorry, I was wrong. I don`t know why scripts above works different :(
