"Error saving to folder: DOMException"

• Cause: Folder permissions or browser security
• Solution: Files will auto-download to Downloads folder

"Failed to decrypt - Wrong passphrase?"

• Cause: Incorrect passphrase or different iterations
• Solution: Verify exact passphrase and iteration count

"Tray icon creation failed"

• Cause: System tray limitations
• Solution: Application will work without tray, restart may help

1. For Large Files:

   • Use lower iterations (100k-250k)
   • Close other applications
   • Ensure sufficient RAM

2. For Better Security:

   • Use higher iterations (500k-1M)
   • Use stronger passphrases
   • Encrypt in smaller batches
