Say I have a 5 GB file. I want to split it in the following way.
First 100 MB is on the file
The rest go some reserve file
I do not want to use readalllines kind of function because it’s too slow for large files.
I do not want to read the whole file to the memory. I want the program to handle only a medium chunk of data at a time.
You may use BinaryReader class and its method to read file in chunks.
