AI Deleted My Files By Mistake. Here's What Actually Happened and the Lesson.

I want to tell you about something that went wrong yesterday, because the honest stories matter more than the polished ones, and this one comes with a genuinely useful warning.

I asked AI to do something simple: gather a batch of duplicate folders into one place so I could review them and delete them myself later. A tidy-up job. Completely routine.

Except it didn't go to plan.

What happened

Instead of safely moving the folders, the AI deleted them. Not because I told it to, I never asked it to delete anything, but because of how the "move" actually worked behind the scenes. What is even scarier is the first time it moved files for me it actually told me it had no capability to delete files directly off my computer. So I was under a false sense of security.

Here's the thing I didn't realise: when AI "moves" a file, it's not one action. It's two. It copies the file to the new place, then deletes the original. Normally you'd never notice, because both steps happen in a split second and both work.

But yesterday, the environment had a wobble, a genuine technical outage midway through. The copy step silently failed, while the delete step went ahead anyway. So the folders got removed from where they were, and the copy that was supposed to catch them never actually landed.

Gone. Not in the folder. Not in the trash. Just gone.

Why I'm not actually upset

Here's the lucky part: these were duplicate files I was going to delete anyway. And they were Canva exports, which means the originals still live safely in my Canva account, nothing genuinely lost.

But it gave me a proper jolt, because I immediately thought: what if these had been files I actually needed?

That's the real lesson, and it's worth sharing.

The lesson for anyone using AI with their files

AI agents are genuinely brilliant, I use them constantly and they've saved me hours. But this was a real reminder that "move" and "delete" are not casual commands when you're handing them to an agent working on your actual computer.

Here's what I'd tell you, from experience now rather than theory:

Back up before you let AI touch anything important. If it's backed up, a mistake is an inconvenience. If it's not, a mistake is a disaster.

For anything you truly can't lose, ask AI to copy, not move. Copying leaves your originals exactly where they are. You stay in control of the actual deleting in your own hands, in Finder, when you're ready.

Check the destination yourself before deleting originals. Don't take "done!" as proof. Open the folder. See the files with your own eyes. Then delete.

If anything seems glitchy or unstable, stop. That's exactly when things go wrong.

The honest takeaway

I still completely believe in using AI agents for real jobs, this hasn't put me off at all. But it sharpened something important: the human stays in charge of the irreversible bits. AI does the heavy lifting; you keep your hand on anything that can't be undone.

That balance is everything. And honestly? I'd rather learn this lesson on a folder of duplicates I didn't need than on something that mattered.

Consider this your free warning. Back things up. Copy, don't move, when it counts. And always check before you delete.

Welcome to your future.
