What is the .REZ File Extension?

.REZ File Extension Description:

The REZ file extension is managed and used by Rez, a program assembler and compiler (while DeRez is the decompiling utility), and RezDet, for use in Mac operating systems. The Rez compiler is similar and comparable to popular programming languages such as Pascal, C, or C++. Files of the REZ file extension is built around an all-text entry, and when saved as an output, becomes what is called a resource file. Symantec and Metrowerks have also developed their own versions of Rez, as part of their own plans in integrated development environments.

The REZ file extension allows users to manage computer resources optimally and efficiently. Unlike its predecessors, (Rmaker, ResEdit), files in the REZ file extension are very extensible because of the vast resource listing and types known to it.

When a REZ file extension is created, users are given flexibility with the options provided. The fact that files in the REZ file extension are built around text files indicates its ability to insert useful and descriptive comments about a resource. Comments can also serve as a change log, which proves very useful when the REZ file extension undergoes several developmental and optimization changes by several programmers.

The REZ file extension also supports macros. As mentioned earlier, since Rez is similar to C/C++, symbols can be assigned to the resource types, Ids, and other variables within the file itself. When opened for editing or debugging, header files are a common find in the REZ file extension as well.

Since the REZ file extension is created with text files, there is no incompatibility generating them from other sources. Files of the REZ file extension can be generated from a resource compiler, and has obvious advantages over a resource file editor. Success of the REZ file extension stems from its ability to attach comments on the resources, various resource types, and defined constants assigned with symbols, and data manipulation/maintenance.
