This file is used by World of Warcraft in order to convert texture filename hashcodes into the string that is calling the said texture. There is only one .trs file yet known and it is found in "misc.mpq\textures\Minimap\md5translate.trs" (it is also found in patch.mpq under the same filename). This file is commonly used to convert the minimap texture files in texture.mpq into the hashcode filenames (and vice-versa if needed) in texture.mpq (and patch.mpq).

To avoid having duplicates of all-water minimaps and thus wasting space, minimap textures have been stored using an md5 hash of their content as filename. To map from map tile to minimap file, textures/minimap/md5translate.trs exists. The file contains blocks of tile → filename mappings per map in text form. 

block_header := "dir: " map_basename "\n"
block_entry := map_basename "\map" x "_" y ".blp\t" actual_filename "\n"
block := block_header block_entry+
file := block+
  • map_basename as found in MapRec
  • x and y as in ADT tile coordinates. Note that x is not zero-padded but y is zero-padded to two digits. ("map_%d_%02d.blp")
  • actual_filename is given relative to textures/minimap/
  • note: an earlier version of this page has block_entry := actual_filename "\t" map_basename "\map" x "_" y ".blp\n"
