That’s a clever little experiment! I never really thought about using regular expressions to represent mathematical patterns like multiples of 3, but it makes sense when you look at the binary sequence. Definitely a fun way to explore just how powerful regex can be beyond ordinary text searching.

JsonTools v8.6 is now available for download (it’s not up on the Plugins Admin yet, pending my PR to NppPluginList). Major changes: Fixed potential for Notepad++ to hang or crash due to: RemesPath queries with a for loop over an empty array Maliciously crafted schemasToFnamePatterns.json config file RemesPath queries that generate too-deep JSON (which previously could have caused stack overflow) List of 16 most recently used unique RemesPath queries (stored in config file, accessible by menu command) New control in JSON to CSV form, allowing columns to be listed in the order that they occurred in the first record, rather than in alphabetical order

Regex is definitely the way to go for this kind of filename cleanup in Notepad++. It’s great how a simple search-and-replace can handle a whole list of filenames at once instead of renaming each one manually. Just make sure to test it on a few files first to avoid any unexpected changes.

@Keith-Collyer said: Following a comment chain, I ended up adding a request to the markdig library here: https://github.com/xoofx/markdig/issues/952 Just an update for anybody following this thread: the feature request to implement wireloom was rejected by Markdig, the rendering library used by MarkdownPanel; it’s still possible for the plugin to implement the feature independently — without needing the WebView2 runtime — by back-porting a static copy of the wireloom.js module to the obsolete JavaScript standard that Internet Explorer supports; a working example of such a workflow can be found here; in the meantime, Preview HTML can now render Markdown and wireloom in Internet Explorer (version 11 )¹˙: [image: 1792597807908-preview_html_v148_ie11.gif] ¹˙ For Windows 7 users, that means ensuring update KB2841134 is installed, and “View as IE11” has been selected on the plugin menu: [image: 1792597754475-preview_html_win7_ie11_mode.png]

Hi @Karen3D — one more angle worth checking, specific to the Windows 11 update scenario: session.xml is only written when Notepad++ exits cleanly. Windows updates are notorious for restarting the machine and killing running apps before they can save, so the session file can end up out of date or empty even with “Remember current session for next launch” ticked. A couple of quick checks that fit an IT-managed work laptop: Close Notepad++ yourself before restarting or shutting down, and confirm in Task Manager that no notepad++.exe process is left hanging around. A leftover process can hold on to the old session. Open a couple of files, close Notepad++ normally, then check the timestamp on session.xml in %AppData%\Notepad++. If it has not been updated, the write itself is being blocked — roaming profiles or redirected folders on corporate machines are a classic cause. If your files live on network drives, make sure the drive mappings are unchanged after the update. Notepad++ quietly skips files it cannot find at start-up. Worth ruling these out before going any deeper.

I think keeping discussions focused on the original topic helps everyone get more useful answers. At the same time, related side discussions can be valuable when they add context or share practical experience. A clear distinction between the main topic and tangential advice makes the community easier to follow.
