I have a SanDisk Ultra USB 3.0 Flash Drive 64 GB. Currently it has about 20% of the memory used.
I have received pictures from 2 different photosessions from the same photographer. All pictures appear to be JPG type. They range from 5 to 25 MB. The size of the first photosession is around 5 GB (contains one folder). The size of the second photosession is around 20 GB (contains 6 folders).
I was able to save only the pictures from the first photosession for some reason. When I copy the pictures from the second photosession all in one go or one by one I see the folders/file names saved on the flash drive but when I click to open any picture nothing happens. The size of the used memory has increased by 25 GB, however I am able to open only pictures from the first photosession.
I am also able to save and open other file types like Doc and pictures from Iphone etc.
I formatted the flash drive once already, however when I copied all the photos back to the drive I was able to open all of them except any from the second photosession.
Please help to resolve this mystery!
Thank you very much!
