#  Copy ORF files from Olympus camera card to D: drive using WSL:
#  1. make mount point in WSL: sudo mkdir /mnt/e
#  2. mount the memory card in WSL: sudo mount -t drvfs E: /mnt/e
#  3. run this script to copy files into subfolders <DST>/<year>/<yyyy-mm-dd>
#  4. remove the memory card from WSL: sudo umount /mnt/e
