This is probably an unpopular opinion but I think that Windows has the correct filesystem behaviour here for the end user. Case preserving but case insensitive.

This is probably an unpopular opinion but I think that Windows has the correct filesystem behaviour here for the end user. Case preserving but case insensitive. Because realistically would normal people (not programmers) really want to have "Resume.txt" "resume.txt" and "RESUME.txt" all on their system rather than just one of them? Though I suppose in these more modern non command line times it doesn't matter as much as it did before.
