+ /ls2 has a special feature to set limit size of recovery files directly.
+When both "/ls2" and "/lr(limit size)" are set,
+setting number of /lr is recognizned as file size instead of number of blocks.
+In this usage, setting limit size must be less than 2 GB.
+If you want max 100 MB each file size, set like these; /ls2 /lr102400000
+Because the calculation ignores packets, you may set a bit smaller size.
