hfs doesn't support other languages at the moment.
it will in the future.
some impatient people translated it by editing resource with "resource editor".
but this method leads to incomplete results, so others decided to edit the sources (you can find on the hfs download page) and to recompile by using "turbo delphi".
this forum board is called "other languages" because is supposed you to post in a non-english language. Has nothing directly to do with hfs translations.
