copyFileToDirectory public static void copyFileToDirectory( File srcFile,Ĭopies a file to a directory optionally preserving the file date. Parameters: srcFile - an existing file to copy, must not be null destDir - the directory to place the copy in, must not be null Throws: NullPointerException - if source or destination is null IOException - if source or destination is invalid IOException - if an IO error occurs during copying See Also: copyFile(File, File, boolean) It is not guaranteed that the operation will succeed.
