What is a CUB file

CUB files mostly belong to Unity.

Game Asset Archives: Many CUB files are used by game engines. For example, a compressed Unity Binary file stores game resources for the Unity engine. A similar format, the CUBE Engine data package, is used by Cube World. Check details at Unity if your file comes from a game.

Time Series Data Files: Some CUB files act as data logger formats that record sequential measurements. They store time series data for further analysis.

OLAP Cube Files: Other CUB files use the Microsoft Compound structure to hold multidimensional data. These are known as OLAP cube files in business analysis. More information is available at Statista.

Airspace Files: A few CUB files include airspace information used by systems such as SeeYou. You can find further details at Naviter.

Planetary Image Files: Certain CUB files are image formats used in planetary science. Known as IsisCube image data files, they are handled by ISIS3. Visit USGS ISIS for more on this format.

How to open CUB files

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

CUB file format:

Every file has a defined file format, i.e. how the data is arranged in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). 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. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the CUB files is as follows:

The CUB file ending includes different formats for the applicable programs. The two most common formats are as follows:

25% of all CUB files use the same file format, which can be identified by the letters "õãô" at the beginning. They consist of unreadable binary data. The files are on average 2 MB in size and range from 710 KB to 390 MB. It is a modern file type. A usual file name is Game.cub or Game_en.cub. Files like these are sometimes connected to curtain, irony, data and hires.
15% of all CUB files have no uniform signature. If you open these files in a text editor, you can view and read the content yourself. CUB files are between 5 KB and 1 MB in size. A usual file name is 20180601.CUB.

All other CUB files (60%) have no consistent format, often e.g. SeeYou Airspace, Isis Cube data, DOC, Generated, Object and cub. The category is cube, airspace, global, uvvis, adorned or func. If you want to find out what your CUB file contains, drag and drop it onto this page.

How to solve problems with CUB files

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