A. 1. Reorganize Your Files: Ensure that your music files are organized in a consistent folder structure on your device. This can help the app locate them more easily. 2. Use the 'Rescan' Feature: If Flacbox has a rescan option in the settings, use it to refresh the library and help the app find your files again.

B. 3. Manually Locate Files: If the app forgets file locations, you may need to manually re-add them by navigating to the file location within the app.
