> Windows doesn’t have it at the file system layer, NTFS is case sensitive. I think the common phrasing is "case-aware, not case-sensitive".

  No, NTFS has always been at least optionally case sensitive; current Windows versions even allow case-sensitivity to be controlled on a per-directory basis[1], which even works for (some) Win32 programs: Microsoft Windows [Version 10.0.22631.3593] (c) Microsoft Corporation.

That's way worse than just putting it on the file system. Now you have hidden information, that you can't ever change, and may or may not impact whatever you are doing.

    I think what they mean is if you somehow had two files with the same name but different cases (as NTFS supports this) it would be impossible to fix with win32 calls
