And further to @Alan-Kilborn’s query: you do understand that, while Notepad++ does it’s best to keep unsaved changes in the temporary session-snapshot-and-periodic-backup folder, it does not guarantee that the OS won’t crash, causing the loss of some or all of those files. If you have 1-2 files worth of data loss from that, that’s horrible (as many, many posts have proven, over the years). But you have what is likely a hundred or more unsaved files in that screenshot. Which means if your OS gets in a bad mood, or if something interferes with a Notepad++ update process, you would lose huge amounts of data.
Please, for the sake of all that information that I am sure you actually care about, please look into a way to save files to meaningful locations and institute appropriate backups for mission-critical data. Because I’d hate for you to be the next unfortunate soul to lose all their unsaved changes, and the best we would be able to tell you is “maybe try Recuva”. That stinks, for everyone involved (but mostly for you).
We have a Backup FAQ to help you make informed decisions about your own saving and backup schemes. And I encourage people to use external backup software, and/or version control software, as appropriate.
Please, PLEASE, don’t just continue working with a hundred or more unsaved files, hoping that nothing will ever go wrong.
