Method

voidcopyFile(File input, File output)
Helper function to copy the file. 
FileInputStream inputStream = new FileInputStream(input);
FileOutputStream outputStream = new FileOutputStream(output);
int lengthStream;
byte[] buff = new byte[1024];
while ((lengthStream = inputStream.read(buff)) > 0) {
    outputStream.write(buff, 0, lengthStream);
outputStream.close();
...
voidcopyFile(File inputFile, File outputFile)
Copy a file from one location to another, using buffered writing 
OutputStream out = null;
InputStream in = null;
try {
    in = new FileInputStream(inputFile);
    out = new FileOutputStream(outputFile);
    byte[] buffer = new byte[64000];
    int bytes_read;
    while ((bytes_read = in.read(buffer)) != -1) {
...
voidcopyFile(File inputFile, File outputFile)
Copies the content from inputFile into outputFile. 
InputStream is = null;
OutputStream os = null;
try {
    is = new FileInputStream(inputFile);
    if (!outputFile.exists() && !outputFile.createNewFile())
        throw new IOException("Failed to create " + outputFile.getAbsolutePath() + ".");
    os = new FileOutputStream(outputFile);
    byte[] buf = new byte[1024];
...
voidcopyFile(File inputFile, File outputFile)
Copies the contents of any disk file to a specified output file. 
File parent;
FileInputStream in = null;
FileOutputStream out = null;
CRC32 crcSum;
int writeCrc;
if (inputFile == null | outputFile == null)
    throw new IllegalArgumentException("null pointer");
if (inputFile.equals(outputFile))
...
voidcopyFile(File inputFile, OutputStream os)
Utility method to copy a file into an java.io.OutputStream . 
FileInputStream fis = null;
try {
    fis = new FileInputStream(inputFile);
    byte[] buffer = new byte[1024 * 1024];
    int n = 0;
    while ((n = fis.read(buffer)) != -1) {
        os.write(buffer, 0, n);
} finally {
    if (fis != null)
        fis.close();
booleancopyFile(File of, File nf)
copy File 
InputStream in;
try {
    in = new FileInputStream(of);
    OutputStream out = new FileOutputStream(nf);
    byte[] buf = new byte[1024];
    int len;
    while ((len = in.read(buf)) > 0) {
        out.write(buf, 0, len);
...
voidcopyFile(File oldFile, File newFile)
Copy file contents. 
FileOutputStream out = null;
FileInputStream in = null;
try {
    out = new FileOutputStream(newFile);
    in = new FileInputStream(oldFile);
    byte[] buf = new byte[4096];
    long size = oldFile.length();
    long copied = 0;
...
booleancopyFile(File oldFile, String newPath)
copy File 
if (!oldFile.exists() || !oldFile.isFile()) {
    return false;
InputStream in = null;
FileOutputStream fos = null;
try {
    int len;
    in = new FileInputStream(oldFile);
...
voidcopyFile(File orig, File dest)
copy File 
FileInputStream fis = new FileInputStream(orig);
FileOutputStream fos = new FileOutputStream(dest);
copyData(fis, fos);
booleancopyFile(File orig, File dest, boolean overwrite)
copy File 
if (!orig.exists() && !orig.canRead())
    return false;
if (dest.exists() && !overwrite)
    return false;
try {
    InputStream in = new FileInputStream(orig);
    FileOutputStream out = new FileOutputStream(dest);
    return copyStream(in, out);
