If you replace "function listallpaths" with param and get rid of the surrounding {} like this..

param([string]$fromFolder, [string]$filter, [string]$printfile)
Get-ChildItem -Path $fromFolder -Include $filter -Recurse -Force -Name > $printfile

You will have a script file that you can call as required.

As Matt alluded to, by declaring the function, when you called the script, it would create the function and then exit. A PowerShell script is basically a function stored in a file (without the surrounding braces.. they are implied), where the function itself would be stored in memory.
