I want to split a very big file into several parts. and then assemble them in another directory with several thread to accelerate copying. How can i do?? Thanx very much!
The speed of copying a file is going to be limited by your disk I/O system. Splitting the job into threads is not likely to help at all. If you want to try it though, you can use the RandomAccessFile class. That should allow you to read and write "simultaneously" to various positions in the file.
