Encountered a problem while ftp the language file to server

[joseph21]

Attention of Ig-Oh theme:

Error1: You should put "Modifications.chinese-simplified.php" on the "languages" directory ( http://www.site.com/forum/Themes/igoh11rc2/languages/ ) in the theme of Ig-Oh.

Question1: Do I need to copy all the chinese langauges folder to the Ig-Oh theme /language folder?

Error2:Copy "Modifications.english.php" of the "languages" directory of Ig-Oh onto the first. Next, rename it according to the language for which you use the file.

Questin2: I don't get this part.. where is this directory of Ig-oh on the first? And what name should I rename it to?
