The uz2 file extension belongs to a compression format used by Epic Games' Unreal Tournament 2003 and Unreal Tournament 2004 for Microsoft Windows. Servers use these files to reduce the size of game content sent to players.
A uz2 file can contain a compressed map, mod, or other game data. After the download finishes, the Unreal Tournament client decompresses the file, installs the content, and makes it available so the player can connect to the server.
Use Unreal Tournament 2003 or Unreal Tournament 2004 on Microsoft Windows to process a uz2 file. Normally, the game receives and decompresses these files automatically when connecting to a server that provides missing content.
Double-clicking a uz2 file usually does not provide a useful way to view it separately from the game.
A uz2 file is not normally converted to another format. The Unreal Tournament game decompresses it automatically and produces the original game content, such as a map or mod, for use by the game.
