What is an .CUB file?

.CUB is Analysis Services Cube File

Data file created by Analysis Services, a component of Microsoft SQL Server; stores a "cube," which is a collection of structured data exported from a data source; includes the data schema as well as the data itself; often used for performing Online Analytical Processing (OLAP) analysis.

Analysis Services cubes can be accessed from a live source using SQL Server's PivotTable Service component. Cube files can also be used for offline analysis in Microsoft Excel. For example, OLAP cubes generated from Analysis Services can be opened and analyzed in Excel and saved as offline cube files.
