This is what modern software development looks like with Claude Code.

👍😊😉 Thank you, Claude, for your endless wisdom and your saint‑like patience with me.
Without you, I’d probably have ended up in a metaphorical trash bin by now.

# Easy Robocopy interface - ERi-Backup-App · v1.7.5.1

A lightweight, modern Windows backup utility built with PowerShell and WinForms, powered by Microsoft's robust Robocopy engine.

## What it does

- Mirrors a source folder to a destination folder using Robocopy (`/MIR`), keeping the destination in perfect sync with the source — or copies a single file to a destination folder when running in file mode

- Runs the backup fully asynchronously — the UI stays responsive even when copying to slow or removable drives (USB sticks, external HDDs)

- Displays live Robocopy output in real time while the backup is running

- Optionally performs a SHA256 checksum verification after each backup to confirm every file was copied correctly (also runs in the background)

- Optionally wipes the destination before copying for a clean-slate backup

- Writes a detailed log file for every backup run, plus a separate checksum report when verification is enabled

## Additional features

- **Source mode toggle** — switch between folder mode (📁 `/MIR` sync) and single-file mode (📄) directly in the UI; the mode is reflected on the button label and persisted in profiles

- **Live path reachability check** — each configured path shows a color-coded indicator (● green = reachable, ● orange = not reachable); the *Start Backup* button is automatically disabled when any path is unreachable

- **Write-access test for source folder** — beyond checking existence, the app writes and immediately deletes a small test file to verify the source folder is truly accessible (e.g. detects encrypted/locked cloud folders that appear reachable but are not yet decrypted)

- **Split status bar** — general backup messages on the left, path status summary on the right, always visible at a glance

- **Settings dialog (⚙)** — configure language and default log path in one place; tooltip shows the dialog name in the active language

  - **Default LogFile Path** — optionally pre-fill the log folder path automatically on every app start and reset; toggle ON/OFF with a single checkbox

- **Clean startup** — source and destination paths are always empty on launch; paths are only loaded via named profiles, avoiding stale or incorrect path combinations

- Save and load named backup profiles (source, destination, log folder, source mode, options) as `.ini` files — ideal for managing multiple backup jobs

- Full multi-language UI — English, German, French, Spanish and Italian, switchable at runtime via the ⚙ button

- Clean dark-themed interface with High-DPI support, works correctly on 4K and scaled displays

- Packages into a standalone `.exe` via PowerShell Studio — no installation required
