# Which copy Storage Studio keeps

For each set of duplicate files on your Mac, Storage Studio recommends keeping the copy you're most likely using — one in a working folder rather than Downloads or Desktop, then the most recently used — and you can always pick a different one.

For every set of duplicate files on your Mac, Storage Studio recommends the copy you're most likely to want: the one in a working folder rather than in Downloads or on the Desktop, and among those the one you used most recently. You can always choose a different copy before anything is removed.

## How the recommendation is made

The rules are applied in order, and the first one that tells the copies apart decides:

1. **Working folder first.** Downloads and the Desktop tend to collect stray copies, so a copy somewhere else is preferred.
2. **Most recent activity.** Among the remaining copies, the one with the latest date wins — whichever is newest of when it was last used, created or modified.
3. **Shorter location.** If the copies are still tied, the one whose location is shortest wins, so the choice is always the same each time.

The set explains its choice in plain words, in a line that starts **Recommended: keep**, for example "it's in your working folder (the others are in Downloads/Desktop)" or "it's the copy you used most recently". The chosen copy carries a **recommended** badge.

## Choosing a different copy

Each copy in a set has a round selector. The recommended copy is selected to begin with; click the selector beside another copy (**Keep this copy instead**) to keep that one. Click a file's name to open it, or its folder to show it in Finder, if you want to compare before you decide.

**Move N to Recycle Vault** then removes every copy except the one you selected. At least one copy is always kept, and the copy you're keeping is checked to be present and readable first — if it can't be confirmed, nothing is removed.

## When you don't pick

- **Clean all — keep the best of each** keeps the recommended copy in every set.
- When [Smart Care](https://storagestudio.us/wiki/smart-care) offers to clean duplicates, it also keeps the recommended copy, and it leaves out any set where a copy changed in the last 7 days.

## Cloud accounts work a little differently

In a cloud account there's no "last used" date to go on, so the suggested copy is the one **nearest the top of the account** — the fewest folders deep. There's no selector there; to keep a different copy, remove the copies you don't want one at a time.
