      • dosAttrsToString

        public static java.lang.String dosAttrsToString​(java.nio.file.attribute.DosFileAttributes dosFileAttributes)

      • exists

        public static boolean exists​(java.io.File file)
        Replaces the exists() method in the File class by taking symlinks into account. The method returns true if the file exists, false otherwise.

        Note: The method returns true, if a symlink exists, but points to a non-existing target. This behavior is different from the classic exists()-method in the File class.

        Parameters:
        file - A file
        Returns:
        Returns true if a file exists (even if its symlink target does not), false otherwise

      • isDirectory

        public static boolean isDirectory​(java.io.File file)

      • formatFileSize

        public static java.lang.String formatFileSize​(long size)
