Because Internet cafes prohibit the use of CMD, I wrote a CMD myself. The splitting and merging tools are:
partition: Split large files such as videos into chunks of 30M size
merge: Merge files split into 30M chunks by partition into the original complete file

Usage demonstration:
Step 1:
Place the software and the file to be processed in the same directory (i.e., folder):
Double-click CMD.EXE, run the command line, and enter "dir", the following information is output:

Directory of B:\sdf

2006-03-23 22:07 <DIR> .
2006-03-23 22:07 <DIR> ..
2006-03-23 22:08 3,584 Merge.exe
2006-03-23 22:08 3,584 Partition.exe
2006-03-23 22:07 51,898,572 伏魔神剑.dat
3 File(s) 51,905,740 bytes
2 Dir(s) 1,488,154,624 bytes free

Step 2:
Run the file splitting tool, enter "Partition" in the command line, and then enter the complete name of the file to be processed, here it is "伏魔神剑.dat"

B:\sdf>Partition

Please input a file for partition: 伏魔神剑.dat
Now I am hard working for you, please wait... ...
Partition: 01伏魔神剑.dat
Partition: 02伏魔神剑.dat
successful do this work, and thanks for you using.

Step 3:
When merging files, enter "Merge" in the command line, and then enter the complete name of the first chunk of the file processed by "Partition", and the file before splitting can be merged

B:\sdf>Merge

Please input the first part of file to Merge: 01伏魔神剑.dat
Now I am hard working for you, please wait... ...
Merged: 01伏魔神剑.dat
Merged: 02伏魔神剑.dat
Successful do this work, and thanks for you using.

Notes:
1. This tool can only split the target file into chunks of 30M each, and does not support users setting the chunk size, but can process files of any file type;
2. The largest file that can be processed is 30*99=2970(M), and ordinary files should not exceed 3G, so it can basically process any file;
3. The two tools should be used together. Since it is only data splitting and merging of the target file, the file size will not change before and after processing, just for easy transmission;
4. This tool is written in pure assembly. The file processing part adopts the most optimized method, and the code is optimized as much as possible to reflect the advantages of writing programs in assembly (small software size, high execution efficiency). If the CPU is P4 and the memory is 256, processing a 600M file takes no more than 30 seconds, and for my own P3, 280 PC, it only takes more than 120 seconds to get it done. In short, the better the PC performance, the faster the processing.
5. Because Internet cafes prohibit the use of CMD, I wrote a CMD myself and give it to everyone. Friends surfing the Internet in Internet cafes may find it useful.

This small tool is quite interesting. Could it be that the owner's USB flash drive is 32MB..

Wow, you're really good!

Good stuff,,,,,

Support,,,,,

This should be a good thing, thank you the building lord's gift!!!!!

Good stuff, I'll reserve a seat first.

Wow, what a talented person!
Collected~~!~

Can you write one with 10,000,000? Thanks a million!

Why don't you add points if everyone thinks it's good? I'll add one.

Good stuff, support one

Is the LZ writing in real - mode assembly?
