Method

FilecopyFile(File aSource, File aDest)
Copies a file from one location to another. 
FileInputStream fis = new FileInputStream(aSource);
File out = aDest.isDirectory() ? new File(aDest, aSource.getName()) : aDest;
FileOutputStream fos = new FileOutputStream(out);
byte[] buf = new byte[8192];
for (int i = fis.read(buf); i != -1; i = fis.read(buf))
    fos.write(buf, 0, i);
fis.close();
fos.close();
...
voidcopyFile(File base, String relfilepath, File targetdir)
copy File 
File sourcefile = new File(base, relfilepath);
File targetfile = new File(targetdir, relfilepath);
if (!targetfile.exists()) {
