The OS will overwrite e.g. the content of "FILE.TXT" with "file.txt" if both exist in the repo. (Or the other way around) As a result, "FILE.TXT" would have the contents of "file.txt" which is typically different, and Git will report "FILE.TXT" as "modified". > > Is this behavior intentional (eg. for performance reasons)? That depends on the definition of "performance". The Git-developpers have not yet implemented a better solution, since most of them do such things in their spare time. As a consequence, we haven't been able to measure the performance on a computer running Git. >If its a bug, can I volunteer to solve it? I would call it a feature, worth to be implemented. And of course, you are wellcome to solve it. I (and probably many others) are happy to help with code-reviews and other tips, hints, suggestions. > Best regards > Paweł
