When you unzip the zip file, it contains all three interview files and the train comming file.

I downloaded and unzipped the audio of the lecture materials, but there is only one file called Train comming. When I tried it on another computer, the file names of the remaining files were in Korean, so the letters were broken and my laptop could not recognize them. I would like to use English names. Also, since there is no music file, I would appreciate it if you could upload it for practice.
