❓ Why Is the First File Usually Audio?

GoodNotes stores files in Attachments/ folder with random names.
🔍 Our detection logic:

1. Extract all files from .goodnotes (ZIP format)
2. Sort files by size (audio = largest → smallest)
3. Force .mp3 extension for compatibility

🚨 Troubleshooting

• "File not found" error?
  → Ensure document contains recordings
  → Check GoodNotes export settings

• File won't play?
  → Rename .mp3 → .m4a (most recordings use this format)

• Slow processing?
  → Works best with files <500MB
