I had to immediate shut down, and I lost about 20 unsaved tabs, is there any way to recover these?
Is there any way to recover unsaved files?
Notepad++ will autosave if configured to do so.
The default "Backup path" is
<Notepad++ install directory>\backup). Look in this directory for any backup files.
Goto menu "Settings" > "Preferences" > "Backup" tab to see your configuration.
If "Enable session snapshot and periodic backup" has been checked then there will a "Backup path" configured.
When was the "Session snapshot and periodic backup" feature introduced?
In version 6.6.x:
As a reminder, the main feature of v6.6.x is Session snapshot & periodic backup - user won't be asked to save unsaved file as he quits Notepad++, and on startup Notepad++ restores the unsaved file and unsaved untitled document of last session. Such periodic backup of unsaved files will protects your data from the PC crashing or power outage.
You can always turn off this feature to get back the old behaviour: http://notepad-plus-plus.org/assets/images/sessionSnapshot.png
