Problem With Head Hunter

[leflibustier]

Hi !
I have a big problem with Head Hunter.
I have ripped the 2 CD with the DC Coders cable, extract the data files from the iso that Tera Term Pro has created and here comes the PROBLEM :

All the data files are on my hard disk but i don't know how to do and which tools to use to minimize some files (like the movies which are compressed with 4xmovie)

I would like to know if someone, who has ripped Head Hunter or someone else, could help me

Thanks !

(Sorry for my poor english, i'm french)
