Name the file extensions in Tableau.

The ones worth knowing:

• .twb — workbook. XML describing sheets, dashboards and connections. No data. - .twbx — packaged workbook. A zip containing the .twb plus extracted data and any local images or custom shapes. - .tds — data source. Connection details, joins, field renames and formatting, without the data. - .tdsx — packaged data source: the .tds plus the data. - .hyper — the extract format, replacing the older .tde since version 10.5. - .tbm — bookmark, a single saved sheet you can bring into another workbook. - .tms — map source. - .tps — preferences, where custom colour palettes are defined.

The distinction that gets asked about is packaged versus unpackaged: anything ending in x carries the data with it.
