11.2.4 Making sure links work in Eclipse Help
The case of file names is significant on the Eclipse platform, even on Windows systems. To avoid case mismatch between links and the files they reference, in some circumstances you might have to specify the following option:
; MakeFileHrefsLower = No (default, leave case unchanged) or Yes (old)
See §18.2.6 Forcing link text to lowercase.
