Music files on iphone disappeared when I tried to add music from PC
I tried to transfer an album from my music file to my iphone using itunes. But itunes couldn’t find the music on my iphone device list.
I checked my iphone and all the music – probably 400 songs or so – were there.
I transferred the album (4 songs) to the device. Now my music icon shows only those 4 songs; all the music previously seen on the iphone music icon is missing.
However, I’m looking at iphone storage and it hasn’t changed at all: 90.9 GB of 128 GB used. So the 10-20 GB worth of music is still there.
How do I recover the music files, or at least, how do I delete them and add back all the files? They are mp3s, for the most part, on my PC. All are my files, from CDs 10-20 years ago; none are downloaded from iTunes.
If I can't get the files back, how can I clear the music files to recover the free space.
