hi i need a simple program to seperate and recombine files. i've searched but i am not able to find such a program. basicly i want to put put a file eg. 100kb txt file AAAAA in one folder and another file eg. 100kb txt file BBBBB in another. the program will combine the files to become a single 200kb ABABABA file. the program must also be able to seperate the 200kb ababab file into 2 100 kb aaaaa and bbbbb files. java prefered. sure this can be written in basic. source code required.
