In http://fileforums.com/showthread.php?t=96465]this topic I fought with obtaining the best possible compression FC4 game and in the end I managed it

Now here we have a problem. We have a single 12.9GB file size. SFK program split this file into 3 smaller parts so that each of them will fit on one single DVD5's. Splitted files have an extension .part*, so we have the file structure: .arc (uncompressed) -> SREP -> lzma (.bin file) and now after splitting -> .part*


The question is: How to "hook up" all this under the Inno Setup installer, eg Glass Black Box?

Can create a .bat script based on SFK program, which would have the task to join the splitted parts into one whole, and then extract the .bin file by INNO. The only problem is that the splitted files must be in the same folder and eventually everyone will be located on a separate DVD's : / This leads also to the fact that the possibility of launching an external application (eg installation of DX, VCRedist or running .bat script) is possible after unpacking the main files (?): /

Any ideas ??

those 3 temp files will be copied to {app} ( specified game folder location chosen by end user ) Then inno / setup would continue the extraction of the files from those 3 files into {app}. Same thing was accomplished with Watch Dogs by BAMsE, & same will need to be done with FC4. There are 2 files that are HUGE 1 at 5GB, the other 15GB !!! 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!
