A little tip I’ve just found, really usefull.
If you need to open a file through Powershell with the default application set up in Windows parameter, just use “Start-process” and the full path of your file

$results |Sort-Object "Size (MB)"|Export-csv "$WorkingDir\Results\$ResultFile" -NoTypeInformation
