Every now and then, my day job pays dividends at home. Shortly before Christmas was one such occasion.
My daughter (a foreign exchange student my family is hosting, but she quickly became a daughter to us) had just spent a weekend with a friend. The friend too was a foreign exchange student from the same country as my daughter, but was near the end of her exchange, and was soon to return to her their home country. My daughter had taken many pictures of their weekend together, and had uploaded them to the friend's computer.
As is commonly the default, uploading the photos to the computer also deleted them from her camera.
By the time she discovered that, the friend had already begun her trek home. Several gigabytes of photos are not hard to transfer over WiFi or with a flash drive ... it's a different story when all you have is a cellphone hotspot with a limited data plan, or a costly and rate-limited airport wireless service.
Much to my wife's chagrin I am a sucker for my daughters' pleas for help. That holds true whether from the daughters born to my family or the daughter we are hosting. Just about any dad would say the same. Fortunately, one doesn't spend twenty years in technology and digital forensics without learning a few tricks.
