See code below, taken from http://www.coderanch.com/t/436301/Java-General-intermediate/java/split-file
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import javax.swing.JOptionPane;
public class SplitFile {
    int FRG_FSIZE=0;
    public File[] splitFile(File source,int noFile,int lsize)
        FRG_FSIZE = 1024*5;
        File[] fileFragments = new File[noFile];
        String[] frgfName = new String[noFile];
                String sourceFName = source.getName();
                long sourceFSize = source.length();
                FileInputStream fis = new FileInputStream(source);
                String Fileinfo = new String(sourceFName + "," + String.valueOf(sourceFSize));
                if (lsize != 0) {
                sourceFName = sourceFName.substring(0, sourceFName.lastIndexOf("."));
                int j=0;
                for (int i = 1; i <= noFile; i++) {
                    frgfName[i-1] ="temp\\"+sourceFName + String.valueOf(i)+".splt";
                    fileFragments[i-1] = new File(frgfName[i-1]);
                    FileOutputStream fos = new FileOutputStream(fileFragments[i - 1]);
                    byte[] data = new byte[FRG_FSIZE];
                    int count = fis.read(data);
                    String frgFileInfo = new String(frgfName[i-1] + "," + String.valueOf(FRG_FSIZE));
                if (lsize != 0) {                    
                    frgfName[noFile] ="temp\\"+sourceFName + String.valueOf(noFile+1)+".splt";
                    fileFragments[noFile] = new File(frgfName[noFile]);
                    FileOutputStream fos = new FileOutputStream(fileFragments[noFile]);
                    byte[] data = new byte[lsize];
                    int count = fis.read(data);
                    String frgFileInfo = new String(frgfName[noFile] + "," + String.valueOf(lsize));
               } catch (Exception e) {
                   System.out.println("Error in Splitting"+e);
                    JOptionPane.showMessageDialog(null, "Error in Splitting File \n"+e.getMessage(), "Error", JOptionPane.ERROR_MESSAGE);
                     return null;
        return fileFragments;
  public static void main(String ar[])
  	SplitFile sf=new SplitFile();
	sf.splitFile(new File("Placement.doc"),5,1024);

brunoguimaraes, your answer may split the file but it produces a number of completely useless, unplayable files. A much better solution would to be use part of the Java Media Framework (JMF) as basav_com has suggested.
