It depends on where the files are located. If the files are on a removeable memory card, it’s easy! Just shut down the phone, remove the memory card, plug the card into a PC’s card reader and use any of the gazillion free and paid file-recovery tools available. (Examples.) No card reader? You can buy…

A reader asks: “I thought an old external drive was full, but it shows up as empty and needing format when I plug it in. Is it really unused, or broken?”
Badly scrambled, is my guess. An error during shutdown, or storage, or reboot, may have damaged the disk’s MBR or Boot Sector or GUID table (depending on how the disk was set up). If there were files on the disk, they’re still there, but the OS can’t see or access them. Hard drives in long-term,…

A reader asks: “How many programs, tasks, and games can I keep open with good performance and no lag on a PC with 16GB RAM/i7 8750HQ/GTX 1060 6G?”
The answer is: 17. Or 674. Or 2. Or 4,237. Not all “programs, tasks, and games” are equal. A handful of resource-hungry apps might bring even a top-of-the-line PC to its figurative knees. But you could run hundreds or even thousands of tiny, efficient apps on the same machine. Sorry, there’s no way to answer…
A reader asks: “What do I do with the USB drive that I found in a department-store changing room?”
You have four choices: a safe and ethically positive one; a probably-safe but ethically murky one; a maybe-kinda-sorta-safe one, also with murky ethics; and a totally unsafe one, with murky ethics. The 100% safe choice is not to keep the drive. For one thing, the person who lost the drive might need it or its…

A reader asks: “Do you remember type-in programs from computer magazines in the 70s and 80s?”
Remember them? I wrote some! 🙂 In fact, I believe I wrote the first type-and-run program to appear in a non-computer, general-circulation magazine, at least in the US. Back at the dawn of the PC era, I was a newly-hatched junior editor at New Shelter magazine; a general-circulation publication with 750,000 subscribers; covering things like…
A reader asks: “Over time, does turning on and off my laptop contribute to wear and tear even with an SSD?”
Yes, with one exception; especially if you mean doing a full shutdown, followed by a full restart some time later. All reasonably current PCs have well-developed power-management systems that are designed to reduce unnecessary energy consumption during use, while the PC is idling, and during restart. Because energy consumption is directly correlated with wear-and-tear of…
A reader asks: “How can you fix an SD card which cannot be formatted?”
Q: “How can you fix an SD card which cannot be formatted? Every time I reformat it the files are still there.” A: The card is probably write-protected by hardware; or by software; or is simply broken. Hardware write-protection: Examine the card for a “lock” or “write protect” slider or switch, often (not always) on…
A reader asks: “Have you heard of the TUTAC computer?”
I hadn’t, but I’m glad you asked (thanks!). This was fun to research, not only because it involves an interesting artifact from the early days of computers, but also because it shares a concept with Bandersnatch, the Netflix choose-your-own-ending movie! TUTAC stands for “TUTorial Automatic Computer,” a device that existed only on paper, in the…
