The Windows filesystem API supports CS file- and directory names just fine. It can be enabled on a per-directory basis like so: > fsutil.exe file setCaseSensitiveInfo C:\folder enable NTFS had support for this for decades now - it was designed that way to be POSIX-compliant. It's shoddy software that lacks support for it, not the OS or the file system.
