Opening SAB Files

The SAB file type is primarily associated with SpaceClaim.

SAB	File extension: SAB
	File type:	binary CAD file

What is a SAB file?

SAB files mostly belong to SpaceClaim. The SAB file is not tied to one single purpose. Depending on its origin, it may be a 3D model file used in computer‐aided design or an audio archive used in game development.
For example, one type of SAB file contains ACIS 3D model data commonly managed by CAD programs such as SpaceClaim. This version stores geometry for 3D design and analysis.
Other SAB files are created for audio purposes – they hold sound data used by game audio systems like CRI Atom Craft and even in tools that log sound levels, as seen with software like Sound Analyzer Pro. In this case, the file acts as a sound archive or compressed data container for game engines such as CryENGINE.

Check the file’s header with a hex editor to determine its internal signature.

Use software specific to its origin: a CAD viewer for the 3D model variant, or the designated game/audio tool if it contains sound data.

Visit official resources such as the Spatial website or CRI Ware for guidance based on your file’s context.

How to open a SAB file

You need a suitable software like SpaceClaim to open a SAB 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. If you cannot open your SAB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a SAB file directly in the browser:. Just drag the file onto this browser window and drop it.

SAB format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. 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. Knowledge is power - this also applies when dealing with unknown or faulty files. Our analysis of the SAB files produces the following result:

The SAB file extension is not common and includes various formats for various programs. The two most popular formats are as follows:

30% of all SAB files have the same signature ACIS BinaryFile. They consist of unreadable binary data. The files are often between 31 KB and 28 MB in size. The file type was developed only in the last few years. The files contain the following words: ACIS BinaryFile, CST MICROWAVE STUDIO and body. Some examples of file names are part1bodies.sab.
20% of all SAB files start with the bytes sabf crucial for this file format. They consist of unreadable binary data. Most of these files are 20 KB to 4 MB in size. The following keywords are characteristic: mtrl, sabf, seq, snd, trk and Music. An example of a file name is bgm_1-01_duodecim.win.sab. Such files are related to duodecim.

All other SAB files (50%) have no consistent format, frequently e.g. Just Cause game data archive and UnityFS. They are often associated with accounting, simple, back or model. Just click the "Choose your .sab file to analyze" button on this page to find out what your SAB file is.

How to solve problems with SAB files

Associate the SAB file extension with the correct application.
Update your software that should actually open binary cad files. Because only the current version supports the latest SAB file format. Search, therefore, e.g. on the manufacturer website after an available SpaceClaim update.
To make sure that your SAB file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
