What is a REZ file?

File with a .REZ extension contains resources – content of a game, such as different types of objects, maps, music and sounds or a net with textures. REZ files are used by the shooter-games based on the Lithtech game engine, developed by Monolith Productions and Microsoft.

Content of most of the REZ files can be modified with the lithrez.Exe tool, usually added to a game, or with a specifically downloaded Dragon UnPACKer software or the Game Extractor. It enables implementing substantial changes in the gameplay. REZ files are used in the gaming products of Monolith company, as in Aliens vs Predator or Noone Lives Forever series, or in the Sierra Entertainment productions Die Hard, Jarhead Games Marine Sharpshooter and many others.

Program(s) that can open the .REZ file

How to open REZ files

If you cannot open the REZ file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports REZ among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the REZ file can be found in the table. Now just download and install the appropriate application.

Possible problems with the REZ format files

The inability to open and operate the REZ file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the LithTech Game Engine Resource Format file. Below is a list of possible problems.

  • Corruption of a REZ file which is being opened
  • Incorrect links to the REZ file in registry entries.
  • Accidental deletion of the description of the REZ from the Windows registry
  • Incomplete installation of an application that supports the REZ format
  • The REZ file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the REZ file.
  • Drivers of equipment used by the computer to open a REZ file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the REZ file should operate with your programs without any problem. If the problem with the REZ file has not been solved, it may be due to the fact that in this case there is also another rare problem with the REZ file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.REZ) you have two ways to do it. The first and the easiest one is to right-click on the selected REZ file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the REZ file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Many files contain only simple text data. It is possible that while opening unknown files (e.g. REZ) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
