Royal clerks wrote the Domesday Book on sheepskin in 1086, and you can still see it in Kew. In 1986, the BBC tried a sequel: about a million people wrote about their towns, and it all went onto laserdiscs that needed one specific BBC setup. By 2002, hardly anyone could open it. The sheepskin was doing great.

## Why Vint Cerf Started Worrying Out Loud

In 2015, Vint Cerf, one of the internet's architects, warned scientists in San Jose that we could be drifting into a digital dark age. Nobody guarantees that next year's software will open last decade's files, so your grandkids might inherit a drive full of your life and nothing that can read it.

His fix was an "X-ray snapshot" freezing the file, app and operating system together for a future machine to unpack. Meanwhile, Pew Research found in 2023 that 38% of webpages from 2013 were already gone.

## Three Quiet Ways a File Stops Opening

- Bit rot. Burned CDs degrade, and an unplugged USB stick can slowly leak the charge that stores its data. One flipped bit can smear a JPEG.
- Orphaned hardware. Your thesis on a Zip disk is probably fine. Finding a drive to read it isn't.
- Abandoned software. Adobe killed Flash Player at the end of 2020, and a decade of browser games went dark overnight.

That last one is sneaky: everything looks fine until your computer asks which app to open the file with.

## Formats That Age Better Than Others

Archivists ask a few blunt questions. Is the spec public? Does more than one company's software open it? Does it need anything outside itself, like a font from one office PC? The University of Michigan library's digital preservation guide reaches the usual conclusion: open, popular formats outlast proprietary ones.

PDF passes that test. Adobe opened the spec in 1993, ISO standardized it in 2008, and the archival PDF/A version packs fonts inside the file. That's why records managers tell you to convert to PDF before you archive anything.

For a mix of HEIC photos, TIFF scans and DjVu books, one browser-based file converter beats a separate app for each.

## An Afternoon Spent Rescuing What Matters

Pick the stuff you'd actually cry over (wedding photos, tax returns, Grandma's scanned letters) and gather it from old phones, email and cloud accounts into one folder.

For Word files, Excel sheets, PowerPoints or EPUBs, I'd use an [online PDF converter](https://onlydoc.com/) from OnlyDoc, which works in a browser tab and handles files up to 100 MB. Its OCR tool keeps scans searchable. Keep the originals for future edits.

Then rename things. "1983-06 letter from Lisbon" will make sense to a cousin in thirty years. IMG\_4471 won't.

## Copies, Checkups and the 3-2-1 Rule

A PDF converter does nothing for a file whose only copy sits on a dying drive. Librarians swear by 3-2-1: three copies, two kinds of storage, one of them outside your house.

Once a year, check that a few random files still open. Every five to seven years, move everything to new drives. Save new keepers, like a signed lease, as PDFs right away, before they get buried in Downloads.

## Conclusion

Sheepskin only needs eyes. Your files need a drive that works, a program that still exists and a format somebody supports, and you control only part of that list. Keep open-format copies in more than one place and check them once a year. Do that, and your photos may still be making the rounds at Thanksgiving in 2070.
