This is what modern software development looks like with Claude Code.
πππ Thank you, Claude, for your endless wisdom and your saintβlike patience with me.
Without you, Iβd probably have ended up in a metaphorical trash bin by now.

# Easy Robocopy interface β ERi-Backup-App Β· v1.6.8.1
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 β or copies a single file to a destination folder when running in file mode
- Runs the backup fully asynchronously β 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** β switch between folder mode (π `/MIR` sync) and single-file mode (π) directly in the UI; the mode is reflected on the button label and persisted in profiles
- **Live path reachability check** β each configured path shows a color-coded indicator (β green = reachable, β orange = not reachable); the *Start Backup* button is automatically disabled when any path is unreachable
- **Write-access test for source folder** β 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** β general backup messages on the left, path status summary on the right, always visible at a glance
- **Settings dialog (β)** β configure language and default log path in one place; tooltip shows the dialog name in the active language
Β Β - **Default LogFile Path** β optionally pre-fill the log folder path automatically on every app start and reset; toggle ON/OFF with a single checkbox
- **Clean startup** β 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 β ideal for managing multiple backup jobs
- Full multi-language UI β English, German, French, Spanish and Italian, switchable at runtime via the β button
- Clean dark-themed interface with High-DPI support, works correctly on 4K and scaled displays
- Packages into a standalone `.exe` via PowerShell Studio β no installation required
