@harmansinghdeepkandhari ,

You don’t need to quote your name at the beginning of every topic (which makes it harder to understand what your question is about). And you don’t need to start by introducting yourself in every topic; we don’t need your C.V. (especially now that you’ve done it twice), as it has nothing to do with us helping you use Notepad++.

Regarding this question: What are your current Settings > Preferences > Backup settings?

If you give us more to work with, we can do a better job of helping you, though, as @Terry-R said, the FAQ does give our best advice.

If you have specific details related to Notepad++ to add, please include them, so that you can help us to help you, otherwise pointing you to the FAQ is the best we can do…

The User Manual’s section on those scintilla editing commands has been updated to include Notepad++'s default keystrokes for them, so we can more easily point users to the fact that Ctrl+L is LINECUT vs Ctrl+Shift+L is LINEDELETE.

@P-A hasn’t come back since my reply. But I had a few minutes to experiment.

Using the published v8.9.2, I could replicate the problem:

Open fresh v8.9.2 Language > User Defined Language > Define your language… Folding in code 2 style: open = openfold, close = closefold Save as… = SomethingNew open disappears, but close remains Exit and restart Notepad++ Language > User Defined Language > Define your language…, choose UserLanguage: SomethingNew Folding in code 2 style> open still missing, but close remains Add again open = openfold, and close the UDL dialog: it appears to be there, but repeating 6/7 will show back in condition 8 at this point.

But, when I try the same sequence with the bugfix version from PR#17522, it works as expected (openfold doesn’t go missing at all).

That PR will be part of v8.9.3 Release Candidate, expected Mar 14. So it looks to me like the bug has already been fixed.
