I would like to ask you if you have saw a noticement on the download page about .man extension? New web should notify you about need to rename it when using Explorer/Edge.

Hi there, I looked around a bit but couldn't find anything specific about the `.man` extension. Maybe it's better to advise us all not to use the browsers that mess up the files.

When you hover with mouse above the firmware download icon with Explorer/Edge browser you should see details about this problem.
