my function:

function filter-swcluster {    param($path, $folderlist)    $oldswcluster = new-object system.collections.arraylist    foreach ($y in $folderlist) {       get-childitem -path $path -filter $y* | sort { [version]($_.name -replace '^.*_(\d+(\.\d+){1,3})$', '$1') } -descending | select-object -skip 3 | foreach-object { $oldswcluster.add($path + "\" + $_) }    }    write-output $oldswcluster } 

the function call:

$filerswcluster = filter-swcluster $networkpath $swcluster 

the output get:

0 1 \\server.domain\c$\temp\folders\testcluster_1.0.2 \\server.domain\c$\temp\folders\testcluster_1.0.1

you wrap add method [void] class accelerator, hide output, this:

function filter-swcluster {    param($path, $folderlist)    $oldswcluster = new-object system.collections.arraylist    foreach ($y in $folderlist) {       get-childitem -path $path -filter $y* | sort { [version]($_.name -replace '^.*_(\d+(\.\d+){1,3})$', '$1') } -descending | select-object -skip 3 | foreach-object { [void]$oldswcluster.add($path + "\" + $_) }    }    write-output $oldswcluster }
