I connected my phone to the Windows PC with a cable and I moved a file from the SD card. It was a video file I recorded with the phone. The file obviously was deleted by it, but unfortunately something did not go well and the file on the PC became unplayable/corrupted. I know the original file was working. Unfortunately I can obviously not see it any more on the phone(sd card). Is there an PROVEN undelete method you know and trust? Not just a google search. Thank you.
