# Phase 2 Plan 1: File Management Summary

**File management API endpoints and UI for viewing/deleting CSV files from flash memory**

## Performance

- **Duration:** 31 min
- **Started:** 2026-03-11T23:39:10Z
- **Completed:** 2026-03-12T00:10:22Z
- **Tasks:** 4
- **Files modified:** 5

## Accomplishments
- Created file management API endpoints (GET /api/files, GET /api/files/<filename>, DELETE /api/files/<filename>)
- Created files.html template with file list, view modal, and delete functionality
- Added /files route to Flask app for the file management page
- Added Files navigation link to all main pages (Dashboard, Settings, Calibration)

## Task Commits

Each task was committed atomically:

1. **task 1: Add file management API endpoints** - API endpoints for list/view/delete
2. **task 2: Create files.html template** - File management UI
3. **task 3: Add /files route to Flask app** - Route for file management page
4. **task 4: Add Files menu item to navigation** - `1b92754` (feat)

**Plan metadata:** `253b8ec` (from prior session), `1b92754` (navigation)

## Files Created/Modified
- `src/app.py` - Added file management API endpoints and /files route
- `src/templates/files.html` - File management UI with list, view modal, delete
- `src/templates/dashboard.html` - Added Files navigation link
- `src/templates/settings.html` - Added Files navigation link
- `src/templates/calibration.html` - Added Files navigation link

## Decisions Made
- Used /myvscada/logger as primary storage path, falling back to src/data/logger
- File listing returns name, size, and created timestamp for each CSV file
- Used Bootstrap Icons (bi-folder) for Files navigation

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None - all tasks completed successfully.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- File management foundation complete - ready for data transmission (Plan 02-03)
- tidEDA export already implemented in Plan 02-02
