.DS_Store is a hidden file macOS automatically creates in every folder you browse in Finder — if a developer uploads files to your server from a Mac without cleaning these up, they can end up publicly accessible and reveal a full list of every filename in that directory, including ones with no direct links pointing to them.
A Mac Finder artifact that quietly leaks your real directory structure and file names to anyone who requests it — harmless to create, easy to forget, trivial for an attacker to use for reconnaissance.
No .DS_Store files are accessible via direct URL, and your deployment process excludes them going forward.
Fix it, then re-scan — the check confirms itself. No manual checkbox, the scan is the truth.
