Method Detail

### moveFile

    public static boolean moveFile(java.io.File source,
                                   java.io.File dest)

  Moves the source file to the destination. If the destination cannot be created or is a read-only file, the method returns `false`. Otherwise, the contents of the source are copied to the destination, the source is deleted, and `true` is returned.

  Parameters:
    `source` - The source file to move.
    `dest` - The destination where to move the file.
  Returns:
    true on success, false otherwise.

### copyStream

    public static boolean copyStream(int bufferSize,
                                     ProgressObserver progress,
                                     java.io.InputStream in,
                                     java.io.OutputStream out,
                                     boolean canStop)
                              throws java.io.IOException

  Copy an input stream to an output stream.

  Parameters:
    `bufferSize` - the size of the buffer
    `progress` - the progress observer it could be null
    `in` - the input stream
    `out` - the output stream
    `canStop` - if true, the copy can be stopped by interrupting the thread
  Returns:
    `true` if the copy was done, `false` if it was interrupted
  Throws:
    `java.io.IOException` - IOException If an I/O error occurs

### copyStream

    public static boolean copyStream(ProgressObserver progress,
                                     java.io.InputStream in,
                                     java.io.OutputStream out,
                                     boolean canStop)
                              throws java.io.IOException

  Copy an input stream to an output stream with a buffer of 4096 bytes.

  Parameters:
    `progress` - the progress observer it could be null
    `in` - the input stream
    `out` - the output stream
    `canStop` - if true, the copy can be stopped by interrupting the thread
  Returns:
    `true` if the copy was done, `false` if it was interrupted
  Throws:
    `java.io.IOException` - IOException If an I/O error occurs

### fileLength

    public static long fileLength(java.io.File file)

  Returns the length of a file. If it is a directory it will calculate recursively the length.

  Parameters:
    `file` - the file or directory
  Returns:
    the length of the file or directory. If the file doesn't exist it will return 0
