      @Fabian-Santiago ,

      That is exactly the folder I meant and the file we are looking for is nppLogNulContentCorruptionIssue.log as @PeterJones pointed out. I’m sorry for my very inaccurate description before, I really forgot the exact folder on Windows OS and the name of the log file (it appears on very rare and obviously unfortunate occasions).
      So it will be helpful if you could upload that file (or its contents) here but please check to be sure it is not revealing any sensitive data.
      Thanks.

        @pnedev sorry my reply took so long. here you are. it won’t let me upload / attach the log file here so this is the content (there was nothing sensitive in it so this is fully intact):

          @Fabian-Santiago ,
          Thank you. I hope it will be useful and give some insight on the cause of the problem.

            Thanks for the log!

            Do you have your N++ autoupdate set ON? (Preferences -> MISC. -> Enable Notepad++ auto-updater checked)

            @pnedev

            This is the same pattern as in here.

            The relevant thing is the last surprising duplicate of the WM_QUERYENDSESSION log, where the session.xml file evidently gets emptied (“2022-09-14 01:23:48 C:\Users\fabian\AppData\Roaming\Notepad++\session.xml 193/193 bytes are written.”)

            So we are getting a little bit closer - now let’s discuss how this could happen.

            If there were slightly different times in the duplicate log items at the end, I could suspect some N++ multi-instancing problem or N++ zombie/crashed process behind, but we have the same log-time everywhere. So I do not think so.

            If it was a racing condition, the last two WM_QUERYENDSESSION items would probably be mixed together. So I do not think so.

            I’m wondering if it cannot be a coincidence with the N++ autoupdating.

            Any other thoughts?

              At the same time config.xml gets 1032 bytes bigger. Quite a big difference.

                  Maybe it could be interesting to see the content of such config.xml too.

                  Now about something else - I have just checked the relevant N++ shutdown source code and I have the following crazy idea (I have not tested/debugged that yet):

                  • the WM_QUERYENDSESSION and WM_CLOSE messages share the same code part
                  • at the standard (user initiated closing of the N++ app) N++ shutdown, the N++ receives only the WM_CLOSE one from these two
                  • when a Windows restart occurs, while the N++ is still opened, the N++ receives both of them, WM_QUERYENDSESSION 1st and the N++ executes the same code part as the WM_CLOSE, then returns TRUE (when an user did not cancelled the Windows restart/shutdown)
                  • when an app sent TRUE to the Windows OS as a response to the WM_QUERYENDSESSION, that app shutdown continues, so the app should obtain the WM_CLOSE sometime later!
                  • and I think that this “double-execution” of the same code part can be the culprit

                  Look at this part - I think that during the 1st execution all the opened files are closed, so at the 2nd execution the session has not any opened files to store!

                  If I am right, the solution is to handle the WM_QUERYENDSESSION and WM_CLOSE separately.

                    @xomx said in Notepad++ lost track of open files / why?:

                    I haven’t looked at the code myself yet but that is a very good assumption @xomx .

                    @Fabian-Santiago ,

                    Could you also share your Backup settings tab?
                    Thank you once again for the debug input.

                        @xomx , All,

                        I suspect that on occasions the periodic session backup might be triggered while in the process of WM_QUERYENDSESSION but that needs further investigation.

                        BR

                          There is also report mentioning a possible coincidence with a pending N++ auto-update.

                          User has periodic backups enabled too.
