I have a sizeable CD collection, all of which I've ripped and converted to MP3. While connected to my home network, I copied many of these files from my Samba NAS share using IOS's built-in files app to the phone itself. I put all the files in a folder I created named "Music". The copy ended with an error message. But all the files appear to be there (and they are consuming space on the device).
Now, how can I play these? If I browse to the folder in the IOS Files app, and tap on an MP3 file, it just hangs. I also tried some 3rd party apps: "Flacbox", "Nota Player", and even good ol' VLC. With VLC, I can't even see how to access the files I copied. Both Flacbox and Nota Player hang when I try to import the files.
FWIW, I am new to IOS, having come from Android. This process was trivial on Android: copy files (no errors), and there was a great simple, free app I used called "Folder Player" expressly for playing local audio media. How can I achieve a similar result on IOS/iPhone?
