I am looking for some advice regarding file management; specifically photo meta data.
I have approximately 15k photos and videos from various mobile phones backed up in a single large folder.
During one of the back up processes, I lost all of the time metadata. The Created, Modified, Accessed time stamps all now say the date I did the backup.
This is frustrating, and means when sorting by time (e.g. if I put the files on an SD on my current phone) the images are not in chronological order.
The correct creation date is however timestamped in the names of the files (e.g. 20180920_134652.jpg taken on 20th Sept 2018 at 13:46.52).
Is there any way I could fix the meta data?
