A nearly full computer got 8.51 GB of space back through careful, verified cleanup, with a person approving the plan before anything was removed.

**Who:** Isolora's own project: a nearly full computer.

**Challenge:** Free up real space without risking important files.

**What we built:** An inventory, verified duplicate checks, a cleanup plan to review and a saved receipt.

**Result:** 8.51 GB of extra free space, measured and recorded.

## The challenge

A computer that's nearly full slows everything down, but deleting things in a hurry is how important files get lost. The goal was real space back, with proof that nothing important went missing.

## What we built

- **Look before deleting** A full inventory of what was taking up space, and where.
- **Prove it's a copy** Before two redundant archives were removed, 247 extracted photos were checked to confirm they were safely in place.
- **Approve first** A clear cleanup plan to review, so nothing was removed without a yes.
- **A receipt** A saved record of exactly what was removed and how much space came back.

## The result

The saved record measured 8.51 GB of additional free space, with every removed item verified and documented.

Under the hood

## The technology, made simple.

### Tools

- Python
- macOS file tools
- Duplicate verification

Finds what's using space and proves files are true copies before removal.

### What do these words mean?

**Duplicate verification:** Checking that two files really are the same before deleting one.

**Archive:** A single file, like a .zip, that holds many other files.

**Receipt:** A saved record of what was done, so it can be checked later.

## What this means for you

Cleanup should never be a gamble. Look first, prove what's a copy, agree the plan, then keep a record. We bring that same care to every system we touch.
