Anyhow, sounds like my only hope is to try and use Recuva. I’ll give that a shot and cross my fingers that it can somehow be recovered.

Appreciate you taking the time to help with this!

@PeterJones - So does this mean if I accidentally saved a named file that opened as the old version, then I cannot recover what I had before?

If you hit SAVE, then the file on disk in the main filesystem contains the contents that were visible at that time, then as far as I know, you cannot recover it (because it almost certainly overwrote the same portion of disk, or the portion that it freed has since been used by your disk). If you had no other backups of important-to-you files, then that is unfortunate.

But, I think you’re under a mis-impression: if you hadn’t been hitting SAVE at any point in the last 9 months, then the file on disk in your normal “notepad” directory has never been written to in the last 9 months, so you didn’t “overwrite” anything. Notepad++'s peridodic-backup (better known as a “snapshot”) ONLY writes to the %AppData%\Notepad++\backup directory, not to the main file’s location, so it has never saved your file there, so there was nothing to be overwritten. If those backups somehow got deleted (and we cannot know how they did, though the installer/updater does not have code to do anything with that directory, so it seems unlikely to me that the installer/updater is the culprit), then the only place that those files have been written to disk was deleted. (And, as it says in the FAQ, you could try to use Recuva or similar recovery software on the %AppData%\Notepad++\backup directory, to see if there are remnants of the deleted backups)

I replaced my PC last September and created a directory containing all of my notepad files. When I look in that directory, they have not been modified/saved since 9/2/2025. I have had 9 months of updates since then and after today’s update I cannot find the most recent version anywhere.

Then you presumably never hit SAVE anytime in those 9 months, until after you had the problem. That’s sad.

As I said, given your settings, any files with unsaved changes should have been in the %AppData%\Notepad++\backup directory. Unfortunately, you have not given any clue as to the exact sequence of events (nor answered whether it was an unusual “update” procedure, by either going from one type of install to another, or by using “uninstall” first), to help someone debug why, on very rare occasions, people have difficulty with losing their session and/or backup files.

To prevent data loss in the future, I highly recommend either adding Ctrl+S to your frequent keystroke mental pattern, or click the menu entry or toolbar icon, or use the AutoSave plugin (as described in the FAQ I already linked). Given that you hadn’t hit SAVE anytime in 9 months, I highly recommend installing that plugin, then following the FAQ to set it to actually automatically save your files to their normal folders

see the Backup FAQ: section on “Scenario: My (unsaved) files are missing!” for recovery ideas

The only files in the backup directory are files that have unsaved changes when Notepad++ exits; once you have saved the file, it is deleted from there. And even if your session file is overwritten (it should not have been, the Notepad++ installer intentionally does not overwrite it), the files in the backup subdirectory should not have been touched, as the installer does nothing with that subfolder, so that strongly implies that there weren’t unsaved changes in other files. In which case, the original files should still be wherever you had last saved them.

If you had a strange update scenario, it might change the expectation:

• If you uninstalled before you did the update, it might have deleted files in there (though it only does that if you specifically tell it to).
• If you had originally had Notepad++ installed someplace other than c:\program files\notepad++ and the old copy was set to doLocalConf or cloud-config or manual -settingsDir, then the old session file and backup files would be wherever that other copy was looking for it.
  • If you think this is the case, search your drive(s) for notepad++.exe, and anyplace other than c:\program files\notepad++\notepad++.exe that it’s found might give you a clue as to where to look for the backup files from that other instance of Notepad++
