Yep, a command line splitter will help a lot developing MMC, I have stopped updating that because of no good cmd splitter

Good with this splitter is, you can set first piece and following pieces.

All other splitters i tested only allow one slice size for all parts.

7-zip can be used as an splitter, because first and other volume size can be determined, but I can't manage inno to show disk change window using 7-zip splitter

Can you give me an batch example?

Here
Here the first split size is 100mb, second and further more will be 1gb

I think not all. The first big Archives are not usually protected.
For example I have seen that the data1 file of Battlefield Hardline is not protected. Also Crysis 3 & some other games.

There are hidden command

I have a question but please answer me :
is there a program that can combine an application with it's the libraries and to be used like one program
like converting batch file to exe with included files

I wouldn't recommend it. Antiviruses don't like those files, will trigger a lot, mostly silently

I've checked with VirusTotal: here
only 1 that may false positive.
I used this for 4 years ago, there's no virus with Avast.
any types of software would be like Advanced BAT to EXE Pro, they have to inject command like %extd% which means that virus could not helpful. :)

Usually that depends upon what's written in batch language.
may trigger false positives too

If I believe that software, Yes I know may trigger false it.
But somehow the developer wasn't updating software.
I'll have to wait for his update. :)

here is another one > https://www.battoexeconverter.com

I wonder why I didn't make this before.
