Send it to the correct app (Music, TV, Books, etc.)
No iTunes, no third-party players — everything stays native.
❓ FAQ
Can I transfer unsupported formats?
If you try to transfer an unknown file type, WALTR PRO will attempt to convert it. If it’s not compatible, you’ll get a message inside the app.
Does this work over Wi-Fi too?
Yes, all file formats can be transferred wirelessly — but for larger files (like HD videos or FLAC albums), we recommend using a USB cable for speed and stability.
What about voice memos?
If they’re saved in MP3, M4A, or another supported format, yes — you can transfer them and they’ll appear in the Music app.
