 Resource-based MUI system with 27+ locales. Each locale has a directory `np3_LANG_COUNTRY\` containing resource `.rc` files. Language DLLs are built as separate projects in the solution.

+### Adding String Resources
+
+1. Add `#define IDS_MUI_XXX <id>` to `language\common_res.h` (use next available ID in the appropriate range: 13xxx for errors/warnings, 14xxx for info/prompts)
+2. Add the English string to `language\np3_en_us\strings_en_us.rc` in the matching `STRINGTABLE` block
+3. Add the same English text as placeholder to all other 25 locale `strings_*.rc` files (translators update later)
+4. Use `InfoBoxLng()` / `MessageBoxLng()` with `MB_YESNO`, `MB_ICONWARNING`, etc. to display; check result with `IsYesOkay()`
+5. `Settings.MuteMessageBeep` controls whether to use `InfoBoxLng` (silent) or `MessageBoxLng` (with sound) — always provide both paths
+
+### File I/O Flow

+- **`FileLoad()`** (`src\Notepad3.c`) — Main load dispatcher.
+  Calls `FileIO()` → `EditLoadFile()` (`src\Edit.c`)
+- **`EditSaveFile()`** supports atomic save (temp file + `ReplaceFileW`) controlled by `Settings2.AtomicFileSave`
+- **Error handling**: `Globals.dwLastError` holds the Win32 error code after failed I/O.
+  `FileSave()` checks specific codes (`ERROR_ACCESS_DENIED`, `ERROR_PATH_NOT_FOUND`) before falling back to generic error.
+- **File watching**: `InstallFileWatching()` uses `FindFirstChangeNotificationW` on the parent directory.
+  Must be stopped before save (`InstallFileWatching(false)`) and restarted after (`InstallFileWatching(true)`).

+## Python Environment
+
+A Python 3.14 virtual environment is available at `.venv\` for scripting tasks (batch file manipulation, locale file updates, code generation, etc.).
+
+```bash
+# Run a script (from project root, in bash/Cygwin)
+.venv/Scripts/python.exe <script.py>
+
+# Install packages
+.venv/Scripts/pip.exe install <package>
+```
+
+Use this venv instead of system Python (which may not be installed). Useful for bulk operations across the 26 locale `strings_*.rc` files.
+
+## Key File Paths (Quick Reference)
+
+| Pattern | Purpose |
+|---------|---------|
+| `language/common_res.h` | String resource ID definitions |
+| `language/np3_*/strings_*.rc` | Locale string tables (26 files) |
+| `Build/Notepad3.ini` | Reference INI with documented settings |
+| `src/Notepad3.c:FileSave()` | Save flow entry point |
+| `src/Edit.c:EditSaveFile()` | Actual file write logic |
+| `src/Config/Config.cpp` | INI management, settings load/save |
+| `src/Dialogs.c:SaveFileDlg()` | Save As dialog |
