Thanks you senseman, works fine!
@For the guru

DVD5 seems to be possible here but without the game Alice1 (the old Alice American McGee's), with only 1 language and resampling at least the biggest bik file.
I'm not able to do an installer with inno for that, maybe peterf1999 can do it as he did with Duke Nukem Forever. Is the same conversion!
Anyway my steps:
- Delete all other languages file into all sub-directory into Alice2\AliceGame\CookedPC\Maps\Chapters (i have DEU, FRA, INT, ESN, ITA and JPN language's files). Delete all files you don't want (eg: you are italian, delete DEU/FRA/INT/ESN/JPN). You save ~500Mb
- Resampled two bik files C1_111.bik (eg: for me now 83Mb) and C1_116.bik (eg: for me now 58Mb) saving ~86Mb
- Move Movies folder (no need compression because the bik files)
- Fire-up FreeArc and compress Alice2 folder (without Movies). From 5,79Gb to 3,31Gb.
Final iso with .arc file and Movies folder has ~37Mb free, just enough for the installer ;-)
