LogoutThe data extract files are the ones that contain a local copy of the entire dataset or in other words, we take a subset of data from the source.
The Tableau Data Extract files have a “.tde” extension.
They do not contain a file path or information about the data source, workbooks, dashboards, etc in them.
Tableau Data Extract files are useful as they are highly compressed and optimized to improve Tableau’s performance especially when we are using data connections that are slow.
