Those files will need to be further split down into separate parts, then they can be reconstructed during installation.

Ok, I understand the theory, but I don't know how to do this from the technical side

I guess I need to add some code in the INNO script, but my knowledge in this area is still very small

Can you help me and explain exactly how to do that? I would be very very grateful!
