I lost open tabs and probably, files! HELP!



  • Hello. Im always work with open tabs(non saved docs, or pasted text in), or txts with unsaved changes, BUT today when I computer shutdown (several mins ago) Notepad plus ask me save some file because no exists att disk)(which never happens before!) , I say YES and GOT only new1 tab !!! ALL GONE!
    Any help? Pleaseeeeee.



  • welcome to the notepad++ community, @Vlad-Gordiy

    you could look in %AppData%\Notepad++\backup if anything is left, but otherwise you’re out of luck.

    a shutdown will only halt as long as a dialogue window is open.
    as soon as the dialogue is closed, and the timeout for a graceful shutdown has passed, the windows shutdown process will force kill any running application.
    this does not give applications time to save their current state, like the notepad++ session.

    if you use unsaved tabs or files:

    • make sure you don’t shutdown or reboot your pc, while notepad++ is still running.

    • make sure you disable automatic windows update reboot, if you leave notepad++, or any other application, running while you are absent from your pc.

    • make sure you don’t need the unsaved tabs in the future, as a power loss, without an ups or battery pack, will eventually produce data loss or data corruption.



    1. Yes, Im have file right here. How do I can restore tabs back and edited files too?

    2. Always I shutdown this way - click shutdown botton in Windows. And Notepad ++ automtically restore with all tabs and edited unsaved files, after I turn my coputer on! But today, somthing goes wrong and notepad doesnt restore anything! wtf

    Yes, Im have file right here. How do I can restore tabs back and edited files too?

    your backup files will look like this:
    unsaved tabs: new 1@2019-03-20_043157 (tab name, followed by @ and date + time)
    unsaved files: yourfile.txt@2019-03-22_083021 (file name, followed by @ and a date/time stamp)

    • first copy them all to a new folder on your desktop.
    • for unsaved files, rename your backup copy to the original file name, by removing the @ and the date/time stamp.
    • for unsaved tabs, rename your backup copy to the original file name, by removing the @ and the date/time stamp, and add the extension .txt as they don’t have an extension yet.
    • open all files in notepad++ and check if you are lucky and they reflect your unsaved files and/or tabs.

    Did you learn any kind of lesson from this experience?



  • Im always think Notepad++ always save last opened tabs as Firefox or CHrome always do

    why you forgot mention session.xml in notepad++ appdata folder? I just make copy this file and replace wiped folder, and after restart porgrams N++ restore all tabs with all files and scrolls saved!



  • @Vlad-Gordiy

    congratulations, if i understood everything correctly, you have been able to successfully recover your unsaved tabs and files. 👍



  • Thanks for your help, really appreciate it! :-)



  • Back to the same old way of operating!

    And what if the power fails? I always reboot with NPP running and never lost any tabs until version 7.6.3. So I thought it would always recover a session, like Firefox or Microsoft Word… What a surprise when everything disappeared !

    a shutdown will only halt as long as a dialogue window is open.

    …but Windows Notepad halts shutdown even when a dialogue window is NOT open! – NPP should work the same way, as the user expects. (Also, NPP does not implement file locking on the contents of its own temp folder while it is running!?)

    if i understood everything correctly, you have been able to successfully recover your unsaved tabs and files.

    If I understood correctly, it also means that automatic session recovery should be trivial to implement in source with a “clean shutdown” flag and a backup of session.xml

    I think the lesson is for the developers.

    Back to the same old way of operating!

    Which should be supported ! 😁

    You can’t be serious…If a tornado/hurricane comes to your house and smashes your computer and its hard drive into bits and your data is lost…is that something the developers should protect you from?

    Save (ctrl+s, often)…and backup (independently of Notepad++, move copy offsite, also often).



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

    I’ve been using the notepad++ as a persistent sticky pad for snippets of code, error messages and random state for years. The old behavior was incredibly useful. Do I need to make a fork?



  • @Douglas-Dike said:

    The old behavior was incredibly useful

    And the persist-across-exits-or-reboots behavior still exists. It is now, and has always been, a calculated risk on your part to enable it. If you lose data (as the OP of this thread did) because Windows crashed, don’t blame Notepad++; anyone relying on an auto-save to not be corrupted during OS crash is taking the consequences of their own decision: it’s not a danger specific to Notepad++: I’ve lost data because MS Word auto-save feature corrupted both the original file and the periodic auto-backup. I always recommend taking full control of critical data (“save early, save often; commit early, commit often” is my mantra).

    And that behavior is now, and has always been (*) enabled via the Settings > Preferences > Backup > Enable Session Snapshot and periodic backup.

    (*: “always” may be an overstatement. I doubt the feature existed in Notepad++ before Notepad++ existed; I don’t know what version number Notepad++ added the session-snapshot/periodic-backup feature. But as long as I’ve known about that feature, it’s been at that setting.)



  • 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.
