Method

voidrename(File from, File to)
rename 
ensureFileDoesNotExist(to);
if (!from.renameTo(to)) {
    throw new IOException("Unable to rename " + from + " to " + to);
voidrename(File from, File to, boolean overwrite)
rename 
boolean success = true;
if (!from.exists()) {
    throw new IOException("file from=[" + from.getAbsolutePath() + "] not exists.");
if (to.exists()) {
    if (overwrite) {
        success = to.delete();
        if (!success) {
...
voidrename(File oldFile, File newFile)
rename 
rename(oldFile, newFile, false);
booleanrename(File pFrom, File pTo)
Renames the specified file, if the destination does not exist. 
return rename(pFrom, pTo, false);
booleanrename(File pFrom, File pTo, boolean pOverWrite)
Renames the specified file. 
if (!pFrom.exists()) {
    throw new FileNotFoundException(pFrom.getAbsolutePath());
if (pFrom.isFile() && pTo.isDirectory()) {
    pTo = new File(pTo, pFrom.getName());
return (pOverWrite || !pTo.exists()) && pFrom.renameTo(pTo);
voidrename(File source, File dest)
It seems that java doesn't like renaming files across partitions (i.e. 
if (!source.renameTo(dest)) {
    FileInputStream from = null;
    FileOutputStream to = null;
    try {
        from = new FileInputStream(source);
        to = new FileOutputStream(dest);
        stream(from, to);
    } finally {
...
booleanrename(File source, File target)
rename 
if (source == null || target == null) {
    throw new IllegalArgumentException("Input cannot be null.");
return source.renameTo(target);
booleanrename(File src, File dest)
rename 
if (src.exists()) {
    return src.renameTo(dest);
return false;
Filerename(File src, String name)
Renames a file using a string. 
File ret = new File(src.getParentFile(), name);
if (src.renameTo(ret))
    return ret;
else
    return null;
voidrename(File srcFile, String newName)
rename. 
if (srcFile == null) {
    throw new NullPointerException("Source must not be null");
if (newName == null || newName.length() == 0) {
    throw new NullPointerException("newName must not be null");
if (srcFile.exists() == false) {
    throw new FileNotFoundException("Source '" + srcFile + "' does not exist");
