How to Rescue Family Files from Old Computers, CDs and Flash Drives

Many families have a box like this somewhere: an old desktop tower, a stack of burned CDs with handwritten labels, and a few flash drives nobody has plugged in for years. Inside are photos, scanned letters, family trees, and notes someone spent years putting together.

Most of it can still be saved, and you can do much of the work yourself. Here's a simple, careful way to go about it.

What you'll need

A new external hard drive with plenty of room. For most families, 1 to 2 TB is more than enough.
A working computer with USB ports.
An external USB CD/DVD drive if your computer doesn't have one. They're inexpensive and widely available.
A notepad (paper or digital) to keep track of what you've copied.

Step 1: Start with the most fragile items

Burned CDs and DVDs, older hard drives, and cheap flash drives can become harder to read as they age. Start with those. Discs you burned at home in the '90s and 2000s usually deserve the most attention, because home-burned discs tend to hold up worse than store-bought, pressed discs.

Step 2: Copy, don't move

This is the most important rule. Copy files onto your new drive, and leave the originals exactly as they are. Don't delete, rename, or reorganize anything on the old media. If something goes wrong partway through, you still have the original to try again.

Make a folder on the new drive for each source, with a clear name:

CD - Mom's photos 1998 (blue marker)
Flash drive - red SanDisk
Dell tower - Documents folder

That way you'll always know where each file came from.

Step 3: Getting files off an old computer

If the old computer still turns on, sign in and copy the main user folders (usually Documents, Pictures, and Desktop) onto the external drive. Check for other user accounts too.

If the computer won't start, the files are often still fine on the hard drive inside. A USB drive adapter (search for "USB to SATA/IDE adapter") lets you connect the old drive to a modern computer like a flash drive. If you aren't comfortable opening a computer case, ask a tech-savvy relative or a professional.

Before an old computer is donated or recycled, make sure everything you want has been copied and checked.

Step 4: Reading CDs, DVDs and flash drives

Handle discs by the edges. If a disc is dusty, wipe it gently with a soft cloth from the center straight out to the edge, not in circles.
If a disc won't read, try a different drive or computer before giving up. Older drives sometimes read discs that newer ones won't.
If a disc reads slowly or makes repeated grinding or retrying sounds, let it finish. If it keeps failing, set it aside and come back to it (see "When to get help" below).
For flash drives, plug them in, copy everything to their own folder, then safely eject them.

Step 5: Check your copies

After each copy, take a minute to compare. Open the original and the copy side by side and look at the number of files and the total size. On Windows, right-click the folder and choose Properties. On a Mac, choose Get Info. Open a few photos and documents from the copy to make sure they display correctly.

Step 6: Keep two copies in two places

One copy is fragile. Make a second copy of the whole drive and keep it somewhere else, like with a family member across town or in a cloud storage service you trust.

Step 7: Watch for old file types

Some files may not open by double-clicking. That doesn't mean they're lost:

Family tree files often end in .ged, .ftw, .ftm, .rmgc or .rmtree. The .ged (GEDCOM) format is widely supported, and many current family-tree programs can import the others.
Old documents from WordPerfect (.wpd) or Microsoft Works (.wps) can often be opened with free programs such as LibreOffice.
Photos in .jpg, .tif or .bmp usually open fine on any modern computer.

Keep these files even if you can't open them yet.

Step 8: Don't clean up too soon

It's tempting to rename files and tidy up folders right away. Wait. Old folder names, file names and dates are often clues about who, where and when. A folder called "Nampa house 95" can tell you a lot.

Instead, write down what you know while the people who remember are still around. Even a short text file saying "Dad's slides, scanned around 2004, mostly the Boise years" is a gift to whoever looks next.

When to get help

Stop and consider a professional if:

A hard drive clicks, buzzes or won't spin up. Continuing to power it on can make things worse. A data recovery service is the right call.
A disc is cracked, peeling or badly scratched.
You find floppy disks, Zip disks or other older formats you don't have equipment for.
The files are there, but there are thousands of them across many devices, and you'd like help organizing them so the family can actually find things.

A note from us

This guide comes from a project close to home. My mom spent decades on our family history, and it ended up scattered across old computers, CDs and drives. The steps above are how I started pulling it back together.

If you'd rather have help, Clarity Intelligence Systems in Eagle does this for Treasure Valley families. We gather files into one organized archive without altering the originals, and we can add a private AI assistant that answers questions in plain English and shows the source documents behind each answer.
