Wow, Peter…perfect reply. Well, at least until you continued with the “As a consolation prize…” and further on. :)

I guess I have two left hands?!

not at all.
you are solving many things, including other people’s problems.
i would rather guess that i have two left hands, because i was not able to be of help on that issue.

There isn’t a builtin way (ie, you cannot just re-run notepad++.exe with a command-line option to close a specific file). If you know of a way to send Windows API messages from the DOS batch file and/or command prompt, then you could possibly send a message to the appropriate component to close that file inside Notepad++. But any such way that I could imagine would require a fairly strong knowledge of the Windows API and messaging system, and probably knowing a programming language beyond batch file (probably via powershell script, and I’m quite sure through VBScript, Python, Perl, Lua, or any number of other full-featured programming languages).

Purely inside vanilla Notepad++, there isn’t a way to set a auto-close-based-on-inactive-time. Using the PythonScript plugin (or LuaScript plugin), which combines the power of the Python (or Lua, respectively) programming language with direct access to the Notepad++ GUI and editor (scintilla) components, you might be able to create a script using callbacks (described in the PythonScript documentation), plus Python timer-based actions, to take care of that; but it’d be a complicated

@Long-Lăng-Hoàng , welcome to the Forum (at least for your first post),

This community forum is a great place for discussing problems, and asking how to do something, or asking what you’re doing wrong to get a strange behavior, or for finding workarounds to bugs and other issues that aren’t going to be “fixed”/changed.

But if you want a bug fixed in the actual Notepad++ codebase, then this FAQ explains where the best place is to submit such requests. When you do submit an issue as described there, make sure you include screenshots of the “good” rendering and the “bad” rendering. Also, posting a link to the issue here in this topic would be nice, so others can see the progress of your issue.

I still feel that backup of a file should be deleted when the file is closed in npp.

Pretty sure N++ plays it cautiously. Some people are going to want those backups. Closing a file in N++ doesn’t mean in general you don’t want it or its history any longer. A better case could be made for removing backups if you use N++ to delete a file or move it to recycle bin.

Maybe try the Edit menu’s Begin/End Select command. Execute it once at the top of the block you intend to select, move to bottom of desired block, execute Begin/End Select again.

btw, as you use a portable version anyways:

you could try out the portable version of notepad++ 7.6.3 from >>> here <<< extract it to a new folder, and update dspellcheck.
on 7.6.3 run `plugins > plugins admin > updates" and update dspellcheck to 1.4.9
(note: “plugins admin” is only available on portable notepad++ since version 7.6.2)

if dspellcheck is the cause of your issue, you can also update to dspellcheck 1.4.10 manually from >>> here <<< and retry.

if technical informations are of interest to you, you can re-read following dspellcheck issues, based on the research of @guy038 :

Thanks.
Your last line says it all…

thank you for your time and excellent and helpful explanation @Joseph

The document (plain text file) in question is NOT opened by another app but it is cloned to a separate window.

if you are using notepad++ in multi instance with auto backup enabled, it is very important that you don’t open the same document in two notepad++ windows, as they are separate processes and neither one is aware of what has been done at the other window.

instead you should use only one notepad++ window and clone it to the second view:
right click on your document tab, and select clone to other view as seen at the screenshot below.

Imgur

now both copies are using the same notepad++ process, and if you start typing, you will see that both, left and right copies, are synchronised without even saving them.

note: if you want to see the unsynced original statically, for comparison purposes, you can copy it’s content to a new document tab on the second view, so that you can have a look at it any time.

it is also recommended that you disable multi instance completely, if you often have to do this.
go to settings > preferences > multi-instance and set it to default (mono-instance) as seen at the screenshot below.

this way a document will always open as a tab at the existing notepad++ process.
