# Will a Move by age rule move files I still open but never edit?

No. A Move by age rule uses the age you set, but it also asks macOS's own index which files you've **opened recently** and keeps those where they are, even if they're old. So a reference PDF you view every week, or a film you rewatch, isn't moved just because you haven't edited it.

It's a best-effort refinement: if macOS hasn't recorded when a file was last opened, the rule falls back to the age alone. It only ever moves *less* than before, never more. And anything that does move leaves a link, so it still opens in place while the drive is connected.
