Hello, @mpheath, @peterjones and all, @mpheath, thanks for your very informative post regarding the differences between 7z and zip archives. I learned a few things today ! ( I should say… tonight ! ) Luckily, I generally extract all files from the N++ 7z archives ! Best Regards, guy038

Hi, @coises, In my opinion, this option seems more like a way of working than a delete option. So, I think this option should remain active between Notepad++ sessions. Note that it’s presently the case within the N++ Search results panel. But, of course, on re-opening N++, the N++ Search results and the Search++ Results panels are both cleared silently, before any search ! After opening Notepad+ and a first search, involving the N++ Search results or the Search Results panels, you can easily un-check that Purge option if you plan to compare multiple searches ! BR guy038
