      welcome to the notepad++ community, @Douglas-Dike

      What needs to happen to get the old functionality where tabs/files persisted across reboots?

      this code part has not changed.
      what has changed, is that you are probably on windows 10, or worse: on w10 build 1809, which will currently force kill applications on automatic windows update reboots, with a more limited grace period, for a “better microsoft user experience” due to faster rebooting.

      Do I need to make a fork?

      no, you just have to install any of the older versions, which you think worked before, from here:
      https://notepad-plus-plus.org/download/all-versions.html
      to personally verify that notepad++ has not changed regarding “tabs/files persisting across reboots”, but your windows platform it is running on.

      eventually you could also dig out your good old win7 dvd and “repair” win10 with it ;-)

        Please update the code for saving current session from time to time to fix the issue with lost sessions on reboot. This is seriously impacting work with NPP as lost sessions/files is very bad experience.
        Thank you.

            I have encountered this problem a couple of days ago, my laptop had a BSOD and seems that the session.xml was corrupted or lost.

            If the “%AppData%\Notepad++\backup” still has the files, you can create a backup in your desktop and use the following c# program to re-create the “session.xml” file.
            Completely close Notepad++ and execute the following c# script:

            // Restores session.xml file in %AppData\Roaming\Notepad++ 
            // from files stored in %AppData\Roaming\Notepad++\backup
            
            using System;
            using System.IO;
            string app_path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
            string path = app_path + @"\Notepad++\backup\";
            string fullfile = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?> \n<NotepadPlus> \n<Session activeView=\"0\"> \n<mainView activeIndex=\"2\">";
            string endtext = "</mainView>\n <subView activeIndex=\"0\" />\n</Session>\n</NotepadPlus>";
            string entry1 = "<File firstVisibleLine=\"0\" xOffset=\"0\" scrollWidth=\"64\" startPos=\"8\" endPos=\"8\" selMode=\"0\" offset=\"0\" wrapCount=\"1\" lang=\"None (Normal Text)\" encoding=\"-1\" userReadOnly=\"no\" filename=\"";
            string entry2 = "backupFilePath=\"";
            string endentry = "originalFileLastModifTimestamp=\"0\" originalFileLastModifTimestampHigh=\"0\" mapFirstVisibleDisplayLine=\"-1\" mapFirstVisibleDocLine=\"-1\" mapLastVisibleDocLine=\"-1\" mapNbLine=\"-1\" mapHigherPos=\"-1\" mapWidth=\"-1\" mapHeight=\"-1\" mapKByteInDoc=\"512\" mapWrapIndentMode=\"-1\" mapIsWrap=\"no\" />";
            string[] filenames = Directory.GetFiles(path);
            foreach (string filename in filenames) 
            {
                int istart = filename.IndexOf("kup\\")+4;
                int iend = filename.IndexOf("@");
                	
                string entryname = filename.Substring(istart,iend-istart);
                string fullname = filename.Substring(istart);
                
                fullfile = fullfile + entry1 + entryname + "\" " + entry2 + filename + "\" " + endentry + "\n";
            }
            fullfile = fullfile + endtext;
            Console.WriteLine (fullfile);
            // If you want to test the output, comment the line below or change the path.
            File.WriteAllText(app_path + @"\session.xml",fullfile);
            

            This could be done with Powershell too, may look into it so that it is a bit more accessible.

              @sfcfs The last line of the code needs to be changed to

              File.WriteAllText(app_path + @"\NotePad++\session.xml",fullfile);
              

              for it to work seamlessly. If not the user needs to move the session.xml file from the folder %AppData%\Roaming to %AppData%\Roaming\Notepad++

              After that, just start Notepad++ and your tabs should be back.

                Just a clarification:

                @sfcfs said two posts ago:

                %AppData%\Notepad++\backup

                and then one post ago:

                %AppData%\Roaming to %AppData%\Roaming\Notepad++

                The first (%AppData%\Notepad++\*) was correct. The second (%AppData%\Roaming\*) is wrong. See the AppData FAQ. Try it yourself: open Windows Explorer, and paste/type %AppData%\Roaming into the title/address bar and see the error message that pops up; then try %AppData%\Notepad++ and see what happens.

                Other than that mistake (which many people make), that’s a great script, so thanks for sharing.

                Also, it would be nice, for those who aren’t C# experts, if you showed how an average-Joe Notepad++ user, who might not have ever touched C#, could take that C# code and actually compile/run it (without having to install a huge C# environment) – not all Notepad++ are C# programmers, or programmers at all.

                ----

                Addenda: See, for example, this post, where I show errors I get when I tried to compile your script with the .NET framework’s csc.exe using c:\windows\Microsoft.NET\Framework\v4.0.30319\csc.exe recover-lost-session.cs:

                recover-lost-session.cs(6,1): error CS0116: A namespace cannot directly contain members such as fields or methods
                recover-lost-session.cs(13,8): error CS1001: Identifier expected
                recover-lost-session.cs(13,10): error CS1518: Expected class, delegate, enum, interface, or struct

                  Here is a PythonScript implementation of it.

                  See these instructions for how to run this script in PythonScript

                  The script will pop up a dialog. Respond with:

                  1. click YES to load the recovered session immediately
                  2. click NO to save the recovered session into an XML file that you can later load with File > Load Session…
                  3. click CANCEL to ignore the recovered session

                  This is only effective if Settings > Preferences > Backup > Enable session snapshot… was checkmarked before you lost your session file. This is only effective if nothing happened to erase %AppData%\Notepad++\backup or equiavlent.

                  Script: RecoverLostSession.py

                        So if what you typed is correct (5.+.+) you are using a seriously old version. Why haven’t you updated? No-one is going to help you on such an old version. The details listed in this post and several like it all refer to much later versions.
