What is a CUB file?
A .CUB file is a multi-purpose data container. It can store many different types of information depending on the software that created it. Commonly, it is an Analysis Services Cube File developed by Microsoft. These files hold offline OLAP (Online Analytical Processing) data for fast reporting in Microsoft SQL Server or Microsoft Excel.
A .CUB file can also be a game data archive used by the Unity engine, Artifex Mundi, or Techland. In science and engineering, the .CUB extension is used for sensor data logs, aviation airspace data in Naviter SeeYou, Gaussian volumetric data, or USGS planetary image cubes.
How to open CUB files?
Because .CUB has multiple possible meanings, you must know the exact file type before you open it. You can open a Microsoft OLAP cube with Microsoft Excel. You can open USGS scientific data with the USGS ISIS software. However, guessing the right software is difficult. We recommend using viewer.online/cub to identify the actual format of your file first.
Inspecting CUB files online
viewer.online/cub can analyze .CUB files to identify the exact format and creator software. It lets you inspect the file structure, extract readable text, and check whether an online preview is available. This helps you figure out if you have a database file, a game package, or a scientific image.
Best practices and troubleshooting
Do not change the .CUB file extension to another extension. This will corrupt the file. If you need to view the data in another program, you must convert it. You can convert compatible database files to sensible target formats like .CSV or .XLSX on convert.guru.
Summary
viewer.online/cub is useful for identifying, inspecting, and understanding .CUB files without installing heavy software or dealing with compatibility problems. It provides a fast way to find out exactly what is inside your data file.
