Don't use -SimpleMatch because that prevents use of a regular expression, which we can use to extract the needed substring. Here is an example:

$s = "Start : Error : billing 1150116682 not found - exit. Source : /mnt/xxx/roo/foo/aaa/115565841_yyyyy.pdf"
$s | Select-String "Error : .* Source : (.*)" | ForEach-Object {
  $_.Matches[0].Groups[1].Value -replace '\.pdf$', ''
}

The above outputs the string /mnt/xxx/roo/foo/aaa/115565841_yyyyy.

You can do a string split like this:

$array = $parse.split(':') $lastItem = $array[-1]

And then get the item you want from the list. Assuming you know where what you need is.
