Description
CPSC-4148/6648 NIO Assignment
Write a program named FileCopy that uses NIO to: • Split the attached file (concert0.mov) into three parts (concert1.mov, concert2.mov, and concert3.mov) • Create and store the three files in the folder C:\CPSC4148 (do not pre-create the folder). • then, rejoin the three files to produce a copy of concert0.mov named concert0(Copy).mov • “concert0(Copy).mov” should be placed in C:\CPSC4148. • “concert0.mov” should reside local to the program. • Subsequent runs of the program should work without the user having to delete the previously created folder and files. • The copy is successful when the copy is playable to the end.
