Method

voidcopyFile(File targetFile, File file)
Copy file to file 
InputStream is = new FileInputStream(file);
FileOutputStream fos = new FileOutputStream(targetFile);
byte[] buffer = new byte[1024];
int i = 0;
while ((i = is.read(buffer)) != -1) {
    fos.write(buffer, 0, i);
is.close();
...
voidcopyFile(File targetFile, File file)
copy File 
if (targetFile.exists()) {
    return;
} else {
    createFile(targetFile, true);
try {
    FileInputStream is = new FileInputStream(file);
    FileOutputStream fos = new FileOutputStream(targetFile);
...
voidcopyFile(final File from, final File to)
Copies a file to a different location. 
if (from.getCanonicalFile().equals(to.getCanonicalFile())) {
    return;
createNecessaryDirectories(to);
FileInputStream in = null;
FileOutputStream out = null;
try {
    in = new FileInputStream(from);
...
voidcopyFile(final File fromFile, final File toFile)
copy File 
InputStream in = new FileInputStream(fromFile);
OutputStream out = new FileOutputStream(toFile);
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
    out.write(buf, 0, len);

...
voidcopyFile(final File fromFile, final File toFile)
Copy file to file. 
FileInputStream in = null;

    out = new FileOutputStream(toFile);
    streamToStream(in, out);
} finally {
    if (out != null) {
...
voidcopyFile(final File in, final File out)
Copy a file 
FileInputStream fis = new FileInputStream(in);
FileOutputStream fos = new FileOutputStream(out);
byte[] buf = new byte[BUFSIZE];
int i = 0;
try {
    while ((i = fis.read(buf)) != -1) {
        fos.write(buf, 0, i);
    fis.close();
    fos.close();
} catch (IOException e) {
    e.printStackTrace();
booleancopyFile(final File oldfile, final File newfile)
copy File 
FileInputStream fis;
FileOutputStream fos;
int len;
byte[] buf;
try {
    if (!newfile.exists()) {
        newfile.createNewFile();

    while ((len = fis.read(buf)) > 0) {
        fos.write(buf, 0, len);
    fis.close();
    fos.close();
} catch (final IOException e) {
    e.printStackTrace();
return true;
voidcopyFile(final File source, final File dest)
copy File 
if (!dest.getParentFile().exists()) {
    String dir = dest.getParentFile().toString();
    new File(dir).mkdir();
InputStream in = null;
OutputStream out = null;
if (source.exists()) {
    try {
...
voidcopyFile(final File source, final File target)
Copy a file 
if (!source.exists() || !source.canRead()) {
    throw new IllegalArgumentException("Can't read from given source file: " + source.getAbsolutePath());
if (!target.exists()) {
    try {
        if (!target.createNewFile()) {
            throw new IllegalArgumentException(
                    "Can't write to given target file: " + target.getAbsolutePath());
...
voidcopyFile(final File src, final File dest)
Copies a file or directory from one location to another location on a local system.

Note: The destination location must exist, otherwise a IOException will be thrown. 
if (src.isDirectory()) {
    if (!dest.exists()) {
        dest.mkdir();
    final String files[] = src.list();
    for (final String file : files) {
        final File srcFile = new File(src, file);
        final File destFile = new File(dest, file);
