To answer how I can recover overwritten files, first of all, see if there is an older version of the file available. On a Windows computer, if you had turned on File History previously, then it might be able to recover the file. Alternatively, you can search for old versions on OneDrive or other cloud storage platforms. In case of a Mac computer, you can try Time Machine. When there is physical replacement of the original data by new data, then it will be very difficult to recover the overwritten data. Do not write any new files onto the drive on which the file has been overwritten. Some data recovery tools may come handy for you, but they cannot recover data that has been fully overwritten.Notchox can provide you with information regarding data recovery software and overwritten files.
