How to open REZ file?

An often recurring problem with Lithtech Game Engine Resource Format is that REZ is not associated with the correct program file. This is manifested by the fact that REZ files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the REZ file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install UnPACKer

An often overlooked issue is to make sure that UnPACKer is installed on the computer. The easiest method is to use the system search engine by entering the program name UnPACKer in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open REZ files.

Step 2. Create association of UnPACKer with REZ files

However, it may happen that the application itself does not cause the REZ file to open in the UnPACKer application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the REZ file with the UnPACKer application.

Step 3. Update UnPACKer to the latest version

If, however, after binding UnPACKer with Lithtech Game Engine Resource Format there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the REZ file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the REZ file. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the REZ file that we want to open. As a result of the scan, sometimes it is not possible to recover REZ files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of REZ file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair REZ file corruption.
The program can also signal the fact of encryption. The encrypted REZ files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. Copying the REZ file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the REZ file while scanning. If this does not work either, restart the device.
