1. Connect Your MP4 to a Computer: Connect the MP4 device to your computer using the provided USB cable or a suitable card reader if your MP4 uses a removable memory card.
2. Access Your MP4's Storage: Once connected, open the File Explorer or Finder window (for Windows or Mac, respectively) and navigate to the drive or folder representing your MP4 device.
3. Find the Music Files: Locate the music files you want to delete within your MP4's storage. They may be organized by folders, such as "Music" or "Audio."
4. Select the Music: Select the music files you want to delete by clicking on them individually while holding the Ctrl key (Windows) or the Command key (Mac) for multiple selections. You can also use the "Ctrl + A" or "Command + A" shortcut to select all files in a folder.
5. Delete the Files: Once the music files are selected, right-click (Windows) or control-click (Mac) on any selected file and choose the "Delete" or "Remove" option.
6. Confirm Deletion: You may see a confirmation prompt or dialog box asking if you want to delete the selected files. Click on the "Yes," "Delete," or "OK" button to confirm the deletion.
7. Empty Recycle Bin/Trash: If your operating system uses a recycle bin (Windows) or trash (Mac) feature, remember to empty it after deleting the files to permanently remove them from your device.
8. Safely Disconnect: After deleting the music files, right-click (Windows) or control-click (Mac) on your MP4 device in File Explorer or Finder and choose the "Eject" or "Safely Remove" option. This ensures that your MP4 device properly disconnects and prevents any potential data corruption.
Note: If your MP4 has an internal storage with no removable memory card, the process may vary slightly, but the general steps of connecting, accessing files, selecting, deleting, and disconnecting remain similar.
Remember to refer to the user manual or documentation specific to your MP4 device if you come across any variations in the process or have additional questions about managing music on your MP4 player.
