Method

voidcopyFileOrDirectory(File source, File destination, boolean flag)
copy File Or Directory 
if ((destination.isFile()) && (!(source.isFile()))) {
    throw new IOException("Impossible to copy  directory");
if ((source.isFile()) && (destination.isDirectory())) {
    copy(source, new File(destination.getPath(), source.getName()));
} else if (source.isFile()) {
    try {
        copy(source, destination);
...
voidcopyFiles(File originalFile, File destinationFile)
copy Files 
FileInputStream fis = new FileInputStream(originalFile);
FileOutputStream fos = new FileOutputStream(destinationFile);
FileChannel inCh = fis.getChannel();
FileChannel outCh = fos.getChannel();
outCh.transferFrom(inCh, 0, inCh.size());
fis.close();
fos.close();
inCh.close();
...
voidcopyFiles(File source, File dest)
copy Files 
FileInputStream fis = null;
FileOutputStream fos = null;
try {
    fis = new FileInputStream(source);
    fos = new FileOutputStream(dest);
    FileChannel fichannel = fis.getChannel();
    FileChannel foChannel = fos.getChannel();
    long size = fichannel.size();
...
voidcopyFiles(File srcFile, File dstFile, boolean overwrite)
copy a file, allowing to overwrite if the destination already exists 
if (!srcFile.exists())
    throw new IOException("Source file does not exist");
if (!overwrite && dstFile.exists())
    throw new IOException("Destination file already exists");
FileChannel srcChannel = null, dstChannel = null;

...
voidcopyFiles(final File fromFile, final File toFile)
Copies the contents of the input file to the output file 
FileInputStream inFile = new FileInputStream(fromFile);
FileOutputStream outFile = new FileOutputStream(toFile);
FileChannel inChannel = inFile.getChannel();
FileChannel outChannel = outFile.getChannel();
int bytesWritten = 0;
long byteCount = inChannel.size();
while (bytesWritten < byteCount) {
    bytesWritten += inChannel.transferTo(bytesWritten, byteCount - bytesWritten, outChannel);
...
voidcopyFileToDir(File file, File destDir)
Copies file from it's location to destination dir. 
String name = file.getName();
String filename = destDir.getAbsolutePath() + File.separator + name;
File destFile = new File(filename);
destFile.createNewFile();
copyFileToFile(file, destFile);
voidcopyFileToDirectory(String fileFrom, String destinationDirectory)
Obtains the file name from the fileIn parameter Copies the file to the destination directory using the same file name 
File inFile = new File(fileFrom);
String fileName = inFile.getName();
copyFile(fileFrom, destinationDirectory + "/" + fileName);
booleancopyFileToFolder(final String resultFile, final String targetPath)
