How to split a file in place without using buffers?

I am sure that we can create a Buffer and use BufferedReader to read the file using the read(Buffer buffer) method.

I have been trying to check if in place read is possible and want to understand what are the implications and complexities involved. Also, If this can be done in a multithreaded environment.

NIO (New IO) will allow creating memory mapped files with MappedByteBuffer, see:
