Hi, all.

Please tell me how to open a file of a extention "iqzip."
I want to open this file (http://www.millisecond.com/download/library/AAT/).
Although I downloaded it, I could not open it because this file's extension was "iqzip."
I unzipped it, but this file's extension remained "iqzip."
When I tried to change its extension(iqx,dat,exp and so on), Inquisit said "select the language in which this script was encoded."
I don't know which language I can use.

Please help me. 

Thank you,

Kasumi Watanabe
