How to split a large file?

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!

it wouldn't be code that needs to be added to script, but maybe a bat file to be run at end of installation that would copy those part files back together into original form & remove those temp files.

There is only two disadvantage about this file splitting.

When unpacking, twice the original file size will be required.

Another disadvantage would be that all the splitted files should all be present in a folder before merging could take place(unless if TStream is used in an advanced manner). So, if you were planning on making multidisk, you first have to copy all the splits in a directory, then merge all the files into the original archive.(again, more space is required, also time.)
after merging, then after unpacking can take place.

So this is what happens when packing:
Compressing > Splitting

when unpacking(Multidisk)
Regrouping > Merging > Deletion > Unpacking > Deletion

when unpacking(Single Media)
Merging > Unpacking > Deletion

so bro please make a tool

Don't worry I have created it before, just before my PC died. So I know the drill, I just have to make the splitter show a dialog on how far is the split so that a user can understand what is happening and how far the process is.

this is without slides?
pls add too slides with the option preserve aspect ratio example 1280x720
shadow text perfect thanx bro

Bro, this is not IC, it is CIU. I added the split/merge function just like you and pakrat asked.
