A. 1. Convert Audio Files: Use an audio converter app to convert unsupported files into a format that Flacbox can read, such as MP3 or FLAC. 2. Check Supported Formats: Refer to the app documentation to see which formats are supported and prioritize using those formats for your music library.

B. 3. Use Alternative Apps: If you frequently encounter unsupported formats, consider using a different music app that has broader format support.
