China DOS Union

Experts in DOS programming, I want a DOS program that splits files under cmd. Put it as a system file in system32. The functions are as follows:
1. Split files with specified size (basic function)
2. Merge split files (this program can be used to merge and also can be merged with the copy command)
3. Audio and video and other files can be played normally after splitting.
4. Customize the storage directory of split files.
Friends who are proficient in programming, it shouldn't be difficult to compile such a program. Help me with this favor, thank you!!!

Well, lxmxn is developing this thing, and it might come out soon~~

Using split:

C:>split -a1 -b3m Jay-HairLikeSnow.mp3 发如雪

Great guy, thanks.... Is this written by yourself? I can't find it online. Can you write a similar program in C language? I want this code, please help...

The split is something that's been around for a long time. I remember that what we're using now is still the one released a few years ago, but it's really useful. For merging, you can use copy /b

lxmxn is using a version of WinRAR

Thanks

I used to write one with BC3.0, but the source code? Mainly used to 'display Chinese in the character interface', written for programming practice, wait for me to recompile it and put it up later. :P

Just what I needed, not sure if it will work, thanks the LZ

Does split have Chinese parameter explanations? I don't quite understand the English.

Great stuff, thanks a lot!

I want to, but I don't have points

Why do I only get an empty folder when I use it?
