So, now you have to sell about 2200 copies if you want to catch up within 3 years.

That means that once your 2 years of working for free are over, and you're ready to start selling the product, you need to then sell at least 1600 copies of your program every year for $50, and that's not even starting to pay back the debts you may have run up, or just the setback to your bank account from the two years of not being paid. So, if you want to make yourself a decent income, we will just use a ballpark number of $80,000. I would say that at least half of people who somehow lose their data, just write it off as an accident or bad luck, consider themselves screwed. Then, when it comes to pricing the software, you have to think about the fact that not everybody needs data recovery software. I don't know about you, but I'm not willing to work full time for a couple of years without pay. This is something that would take you easily a couple of years to build as a reasonably thought through product on your own, and that's if you are a good programmer working full-time on it.

Why should data recover software be free? Anything that actually works, and even the ones that don't work very well, are the result of thousands of hours of development time. They probably weren't deleted but rather went missing do to some type of damage / corruption of the filesystem. But I'd wager you still won't see the missing files. SD cards are inherently unreliable and essentially disposable devices, I'd consider replacing it at the first sign of trouble.ĭoes mac have a build in option to see hidden files? It would be wise to image the card before scanning it for recovery, in DMDE this is done with: Tools > Copy Sectors, and save to an image file stored on the computer / other external drive. Your files shouldn't be deleting themselves from the card for no reason, this is often a sign that the card is failing. If you need to recover a large number of folders more conveniently, it's $20 for a basic personal license, way more affordable than other garbage like Disk Drill. Its free demo can recover up to 4000 files / 1 folder per operation, no limit on filesize or number of recovery operations you can run for free.

Since you're apparently on Mac (should have been mentioned in the original post) is the closest thing to a free option you're going to get.
