Default Recover deleted files from internal storage, root not required?

Hello everybody,

I have unintentionally deleted all my photos and videos from the internal storage of my Note 3.
Apparently, the only way to recover them would be to root the device (and void tje warranty).
Do you confirm that there is no way at all to manually dump the folder where were the videos from the internal storage as a Virtual Hard Drive file?

I cannot post the links where I read that, as I am a newbie ( not yet allowed)

Is there a hope to recover deleted files without rooting?

I don't wish to root and void the warranty because the phone may be sent for repair bexause of unexpexted reboots. They would notice the rooting (Knox e-fuse).

The firmware is N9005XXUDMJ7

Thank you very much in advance!
