I had some files I transferred from my computer to my iPhone via Zapya and deleted actual files later on

I wanted to recover later and discovered that actual files are nowhere but I can see same files with same size but with .DM extension in my C:\Users\USERNAME\Documents\Zapya\Video folder

I tried removing .DM extension and played on MPC-HC player and also on VLC Player but it does not play

Any idea on how to recover those files?


A file with the .DM extension is a file (often audio) that has been encoded with DRM (Digital Rights Management) copy-protection; used by some cell phones for ringtones and other media clips, but can also be used for digitally signed mobile applications; can only be opened using an authorized cell phone.

Since these files are protected with DRM (Digital Rights Management) copy-protection software, a cell phone must be authorized in order to use them.

  • Do you have any clue how to unlock it? I have that iPhone which I used to transfer that file with – Umair Ayub Jan 17 '19 at 12:45
  • Only the phone that is authorized to use the file will be able to play the file; you'll only be able to play the videos on your iPhone. – Rowan Richards Jan 17 '19 at 12:47
