Automatically Remove Missing Games

📋 Summary

Add an option in LaunchBox for Windows to automatically remove games from the library when their associated files no longer exist on disk

❗ Problem

Currently on Windows:

• LaunchBox can scan for missing ROMs, but this requires manual action

• Libraries do not update automatically when files are removed or reorganized

• Users maintaining collections at the file system level must repeatedly rescan and clean up

For large or frequently changing collections, manual cleanup becomes tedious.

💡 Proposal

Introduce an automatic missing file cleanup option:

• Periodically or on startup, LaunchBox checks whether linked game files still exist

• Games with missing files are automatically removed from the library

• Optional settings:

  • Enable or disable automatic removal

  • Prompt before removal

  • Restrict to specific platforms or folders

📦 Benefits

• Keeps libraries in sync with the file system automatically

• Reduces manual maintenance for large collections

• Supports workflows where ROMs are frequently added or removed

💡 Notes

• Should reuse existing “scan for missing ROMs” logic

• Default behavior should remain manual to avoid surprises

• Clear messaging is needed when games are removed automatically
