+# Phase 4 Plan 07: Localization + Shared Dialogs + Example CSV Resources Summary
+
+**80+ Phase 4 EN/FR localization keys added to resx files, ConfirmBulkOperationDialog and lazy-loading FolderBrowserDialog created, three example CSV files bundled as EmbeddedResource**
+
+## Performance
+
+- **Duration:** 15 min
+- **Started:** 2026-04-03T08:10:00Z
+- **Completed:** 2026-04-03T08:25:00Z
+- **Tasks:** 2
+- **Files modified:** 11
+
+## Accomplishments
+
+- Added all Phase 4 EN/FR localization keys (tabs, transfer, bulk members, bulk sites, folder structure, templates, shared bulk strings, folder browser dialog) — 80+ keys across both .resx files with full Designer.cs accessors
+- Created ConfirmBulkOperationDialog with TranslationSource-bound title/buttons and caller-provided message text
+- Created FolderBrowserDialog with lazy-loading TreeView: root loads document libraries, each library node loads sub-folders on first expand using ExecuteQueryRetryHelper
+- Bundled three example CSV files (bulk_add_members, bulk_create_sites, folder_structure) as EmbeddedResource in csproj
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1 + Task 2: Phase 4 localization, dialogs, and CSV resources** - `1a2cc13` (feat)
+
+**Plan metadata:** (committed with final docs commit)
+
+## Files Created/Modified
+
+- `SharepointToolbox/Localization/Strings.resx` - Added 80+ Phase 4 EN localization keys
+- `SharepointToolbox/Localization/Strings.fr.resx` - Added 80+ Phase 4 FR localization keys
+- `SharepointToolbox/Localization/Strings.Designer.cs` - Added ResourceManager property accessors for all new keys
+- `SharepointToolbox/Views/Dialogs/ConfirmBulkOperationDialog.xaml` - Confirmation dialog with Proceed/Cancel buttons
+- `SharepointToolbox/Views/Dialogs/ConfirmBulkOperationDialog.xaml.cs` - Code-behind with IsConfirmed result property
+- `SharepointToolbox/Views/Dialogs/FolderBrowserDialog.xaml` - Folder tree browser dialog
+- `SharepointToolbox/Views/Dialogs/FolderBrowserDialog.xaml.cs` - Lazy-loading TreeView with SelectedLibrary/SelectedFolderPath properties
+- `SharepointToolbox/Resources/bulk_add_members.csv` - Example CSV for bulk member addition (comma-delimited)
+- `SharepointToolbox/Resources/bulk_create_sites.csv` - Example CSV for bulk site creation (semicolon-delimited)
+- `SharepointToolbox/Resources/folder_structure.csv` - Example CSV for folder structure creation (semicolon-delimited)
+- `SharepointToolbox/SharepointToolbox.csproj` - Added EmbeddedResource entries for three CSV files
+
+## Decisions Made
+
+- FolderBrowserDialog uses `Core.Helpers.ExecuteQueryRetryHelper` (not `Infrastructure.Auth`) — consistent with the established project namespace pattern from Phases 2/3
+- Example CSV files placed in `Resources/` and registered as `EmbeddedResource` — runtime access via `Assembly.GetManifestResourceStream` without file system dependency
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All Phase 4 localization keys available for use in ViewModels/Views (04-08, 04-09, 04-10)
+- ConfirmBulkOperationDialog ready to be shown before destructive bulk operations
+- FolderBrowserDialog ready for use in FileTransferViewModel (source/dest folder picker)
+- Example CSV files accessible as embedded resources for "Load Example" buttons in all bulk tabs
