This would be accomplished in Windows or Linux by entering a file explorer, clicking on the first file, then holding down the shift key as you click on the last file in the group you want. I cannot figure out how to do it in the default "My files" or Cheetah or X-plore file explorers. When travelling, I transfer photos from the camera's mem card to a tablet every day. This means selecting on the order of 200 files at a time. Doing that by clicking in the little box by the file name is -- at the least -- tedious. It is also error-prone.
