What is a FEZ file?

FEZ files mostly belong to FEATool. FEZ files are specialized archives that use the ZIP format internally. They are known as FEA Zip files because they hold finite element analysis data alongside 3D model information.
These files are produced by FEATool and are used in engineering simulation as well as 3D modeling work with CAD applications like Autodesk Revit and tools from Fuzor.
Key details compiled by FilExt.com include:

Compressed Structure: The file is built on a ZIP archive format.

Simulation Data: It stores data for finite element analysis used in simulations.

3D Modeling: It contains 3D model information that integrates with Autodesk Revit.

How do you open FEZ files?

You need a suitable software like FEATool to open a FEZ 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 FEZ file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FEZ file directly in the browser:. Just drag the file onto this browser window and drop it.

FEZ file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. File extension, signature and file format must match; otherwise errors will occur when the file is opened. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the FEZ files looks like this:

The FEZ file extension is not found very often and is mainly used by one program with a specific format. However, the following two file formats are common:

95% of all FEZ files use ZIP compression, so several files are compressed and saved in one FEZ file. A FEZ file contains 3 to 25 files, the average being 7. File names inside are always _serialized_content.xml, ApplicationInfo.xml and \ProjectExtensions\ProjectInfo.xml. You can see the included files and images by renaming the file extension to .zip and then double-clicking it. Most of these files are 15 KB to 9 MB in size. Certain words are almost always found in the files, such as _serialized_content.xml and feaUT. Files like these are sometimes connected to project, takeoff, floor, crossings, section, lining, street, model and place.
3% of all FEZ files start with the bytes FEZC crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. The files are 6 MB to 66 MB in size, with a median of 66 MB. The following filename is common: data.fez.

All other FEZ files (2%) have no uniform format. You can get all the details of your FEZ file by dragging it onto this page or by clicking the button "Choose your .fez file to analyze" above.

How to solve problems with FEZ files

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