Hello Rongzhi,

Sorry, I hadn't seen your message. The file "chineseStrings.txt" has a problem of charset (Windows-1252); it is not unicode, so I cannot read any chinese types. Anyway my chinese is too bad to help you.

Nevertheless, with good dictionaries online you should arrive to translate what you want.
See : http://www.chinese-tools.com/tools/dictionary.html
or this one http://www.chinesedic.com/en/
and don't forget http://translate.google.fr/?hl=fr&tab=wT#en/zh-CN/

Examples with google translate we get:
File = 文件 Wénjiàn
Open = 打开 Dǎkāi
Save As = 另存为 Lìngcún wèi
New = 新 Xīn
Import = 进口 Jìnkǒu
Export = 出口 Chūkǒu
Save = 节省 Jiéshěng
Undo = 复原 Fùyuán
Redo = 重做 Chóng zuò
Delete = 删除 Shānchú

I couldn't tell if this translation is correct.
I should spend hours to check everything.
