Trs files - cmangos/issues GitHub Wiki

The filenames of Minimap textures stored in MPQ Archives are hashed using MD5. The TRS file provides an easy lookup from real pathnames like Azeroth\map00_00.blp to the corresponding hashed filename f16354735dad4e22e175a398a01992ba.blp

TRS is a plain human-readable text file. Every directory is started by a line that looks like

dir: Azeroth

after which a table with two columns (tab-separated) lists the corresponding clear-text filenames and hash filenames like this:

Azeroth\map00_00.blp    f16354735dad4e22e175a398a01992ba.blp
Azeroth\map00_01.blp    3f6b258da2fe615b620d34eaa26bb0cc.blp
Azeroth\map00_02.blp    6e2e4a333dc88a8581c727d3207d04f8.blp
Azeroth\map01_00.blp    1c415ef6183e799c137c959596e34c40.blp
Azeroth\map01_01.blp    8abbe680628429c4c6e6abf286bfed68.blp
