Prototype 2 (1xDVD5)

[The-revenge]

I have a problem. Data2.cab is 551 mb instead of 446 mb. I open with freearc and see that inside this cab there are a redist folder. I think is incorrect, and without this folder (102 mb) the size is correct (abbout 446 mb).
Can I open this cab and delete redist folder and recompress it? What are the option in freearc to extract and compress?
Thank you

EDIT : I'm trying to do this : I open compress.bat and delete the line for create data1 and data3 cab. Then I save bat, move away folder redist and run compress.bat.
Can you show me the list of file into data2.cab fo verify? Ty.
EDIT 2 : don't work
