This is a tiny little PowerShell script that will find any files you have open in Notepad and present them in out-gridview with lines to help with searching. Large files it will prompt you for a pre-search term or a regex to make it usable in out-gridview. Super handy for when you get logs in Outlook and don't want to save them to somewhere spec…
