The music downloaded by HarmonyOS system can't be found in the local ringtone.

Dear, I am glad to answer your question: 1. Open Huawei file management application and click "Internal Storage". 2. After opening the memory, click the "Search" icon in the upper right corner. 3. Enter ".mp3" to enter the search. 4. Find the downloaded music in the search results, select the music and click "Move". 5. Return the directory to the root directory of memory storage. 6. Click Move below to move these music files directly to the root directory. 7. At this time, open the "My" interface of Huawei Music and click "Local". 8. Click "Three Points" in the upper right corner, and click "Scan local songs" in the pop-up options. 9. At this time, you can scan the music files previously stored in the root directory (attachment: if you want to scan the music files received or downloaded by third-party applications, you need to remove them from the folder layer).
