File	File.getAbsoluteFile() Returns the absolute form of this abstract pathname.
File	File.getCanonicalFile() Returns the canonical form of this abstract pathname.
File[]	File.listFiles() Returns an array of abstract pathnames denoting the files in the directory denoted by this abstract pathname.
File[]	File.listFiles(FilenameFilter filter) Returns an array of abstract pathnames denoting the files and directories in the directory denoted by this abstract pathname that satisfy the specified filter.
