AmMstools - PyAB

Game Save Backup Manager for Windows

---

PyAB automatically backs up your game save files so you never lose progress. It monitors save files in real time, captures screenshots, and lets you restore any backup with one click.

Features

• Automatic Backups — timer-based or triggered by file changes (watchdog)
• Game Detection — pauses when the game isn't running, resumes when it is
• Screenshot Capture — saves a screenshot with each backup (auto-detects game monitor)
• Multi-file Saves — supports games with multiple save files (comma-separated)
• Profile System — multiple backup profiles per game with independent settings
• Backup Management — restore, delete, browse backups with context menu
• Screenshot Preview — click to zoom into full-size view
• Backup Limits — auto-cleanup by file count or total size
• Path Templates — flexible path resolution (#Documents#, #Steam#, #AppData#, #ID#)
• Dark Theme — Material Design-inspired dark UI
• Localization — English and Italian, switchable from Settings menu
• Portable Data — user data stored in %APPDATA%/AmMstools/PyAB/
