This file does not exist or has a length of 0 if the RST file had the version signature "VER3.500". For "VER3.501" RSTs, this file exists:
+0 96 BYTEs ? (unused)
+96 5 BYTEs Signature "yAmsz"
+101 WORD Total number of Ufos. Note that this file only contains
Ufos with an Id number > 100, Ufos 1 to 100 are already in
KOREx.DAT. If this field is 100 or less, no Ufos follow
here. The host reduces the size of the Ufo database, so if
the highest existing Ufo Id is 215, you'll find the value
215 here, and 115 Ufo records following.
+103 WORD RST sub-version (currently 1, the "01" in "VER3.501").
--- if "Total number of Ufos" > 100 ---
+105 n RECORDs of 78 bytes each: the Ufo records (see UFO.HST).
--- if "Total number of Ufos" <= 100 ---
+105 5 BYTEs Marker "no000"
