ZAR	File extension: ZAR
	File type:	multi-use data container

What is a ZAR file?

ZAR files mostly belong to Zemax OpticStudio. A ZAR file may look like a single format, but it actually covers several types of data containers. The most common use is as a Zemax optical design file used by Zemax OpticStudio. In that role, the file holds simulation data such as ray tracing parameters and optical system settings.
Other uses include:

Game Archives: Some ZAR files work as a Zelda Archive File or a game resource file. They may store assets for older console games (for example, Nintendo 64) and are sometimes used by emulators like Dolphin or editors such as the CryENGINE Sandbox Editor. You might notice these archives are sometimes labeled as a Binary ZenGin Archive.
Compressed Archives: In some cases, a ZAR file is simply a container compressed with standard algorithms (GZIP, ZIP, or RAR). Such archives can be opened with tools like WinZip, 7-Zip, or WinRAR.
Backup Files: There are even instances where a ZAR file serves as a backup (for example, an encrypted backup like the Astolfo backup used for WhatsApp data).

FilExt.com tips: Opening a ZAR file depends on its origin. If it is from an optical design project, Zemax OpticStudio is needed. When it holds game assets, use a game-specific tool or emulator. And if it is a compressed archive, standard decompression software is the choice. Few realize that the same extension is applied across different industries, each with its own internal structure.

How to open ZAR files

You need a suitable software like Zemax OpticStudio to open a ZAR file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert.

ZAR file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So you need a detailed analysis of a file to find out the format and the associated program. Our examination of the ZAR files comes to the following conclusion:

The ZAR file type includes different formats for the applicable programs. The two most popular formats are as follows:

25% of all ZAR files have the same signature EC 03 00 00. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. The files are on average 150 KB in size and range from 92 KB to 620 KB. This file type is based on cutting-edge technology. Such files are related to zemax, black, forward, zmax, zemaxzar and design.
15% of all ZAR files use the same file format, which have the signature ZAR. These files are binary files, so they do not contain text, but only cryptic characters. The file size is in the range of 12 KB to 1 MB. The files contain the following words: queen, unknown and cmab. These files can be linked to zelda, board and clip.

The remaining 60% of all ZAR files are files with no common format, the following 8 formats exist: GZIP, RAR, ZIP, zar and xTyGWpa. Files like these are sometimes linked to core, prefab or recovered.
