Just like PCs, the smart phone needs backups of what we can't lose. I've see spammers share recovery apps but yet to see those work.
Take what can save and backup to your PC or what have you. What you have now is still unsafe. Where are the backup copies?
I was in the process of moving photos from my mother's internal storage on her Samsung Galaxy J7 to a new (formatted) SD card. I cut the files from her internal DCIM folder and pasted them into the SD card storage. At first, not all of the items transferred, so I returned to the DCIM internal and cut/pasted them again. During the second try, it told me that some items could not be transferred and I was given the option to skip the files or to stop the copy. I believe I selected to stop the transfer. Upon my selection, all of the photos disappeared. All 825 of them...
They are no longer in either location. The data amounts in both places changed to reflect that the photos are gone. They are not in my computer's recycle bin. I tried searching by typing in a fragment of the photos' name (a YYYYMMDD format) but was unable to find them. I'm freaking out because I know that those photos are irreplaceable to my mother, and was only trying to help her organize her storage system given that she was running out of space.
How can I recover the photos lost during cut/paste transfer? While I used my computer to manage the switch, I never put the files on my computer; I performed the transfer in the phone's folders. I tried to use Pandora Disk Drill after reading a bit online, but it recovered over 44,000 photos and I don't know that any of those are the ones I lost, given that the deep scan was searching my computer. I'm not sure how to access "cut" function history to view if the files are somehow stuck in my clipboard. The paste option is not available.
