Situation:
Open a text file in n++, make some modification, press ALT-F4 or Close program. The N++ won\'t ask \"Do you want to save your changes\". Instead it quits
This is actually a great feature. First, Periodic backup is great it can prevent data lost when pc suddenly shutdown or crash.
The feature: don't ask to save files is also great.
For me, I opened a lot of files in notepad, also create a lot of tmp files(I don't want to save these tmp files, but it may be useful for x days), in previous version, when I close notepad++(reboot pc or install new version), it asks me whether save all these files. It's a nightmare.
This feature helps me a lot.
Also there is no data lost - all your data is still there after restart. So really nothing to complaint.
