In addition to the file types mentioned before, there are quite a few other file types associated with Tableau. The following are some of the Tableau file types (with commonly used ones in bold):

• .tbm: This stands for Tableau Bookmark. This is an XML file containing definitions of a static snapshot of a single view and associated data source(s). As sheets can now be copied and pasted from one workbook to another, this file type is largely not needed. You can create a bookmark and import it into other workbooks from the Window menu.

• .tde: This stands for Tableau Data Extract, which is a binary file containing data extracted from another source. The .tde file by itself does not contain information about the original data source.
• .tds: This stands for Tableau Data Source, which is an XML file containing the definition of a data source (server name, file path, and so on) but does not contain the data. You can export a data source as a .tds file by right-clicking on the data source and selecting Add to Saved Data Sources. Any .tds file in your My Tableau RepositoryData Sources directory will show as a data connection shortcut on the Home Screen.
• .tdsx: This stands for Tableau Data Source Extracted, which is a compressed file containing the definition of the data source along with an extract of the data. You may create a packaged data sources in the same way you create .tds files, selecting .tdsx as the file type.
• .tld/.tlf/.tlq/.tlr:  Tableau License Disconnected/ File/ Request/ Return Response file types are used for license activation. 
• .tms: This stands for Tableau Map Source. This is an XML file type used to specify map services and configuration available to Tableau.
• .tmsd: This stands for Tableau Map Source Defaults. This is an XML file containing defaults for map services.
• .tps: This stands for Tableau Preferences. This is an XML file containing preference defaults for Tableau Desktop, including UI elements and color palettes.
• .tsvc: This stands for the Tableau Atom Service file type.
• .twb: This stands for Tableau Workbook. This is an XML file containing definitions for all sheets, data sources, preferences, and formatting. It does not contain any data.
• .twbx: This stands for Tableau Packaged Workbook. This is a compressed file containing the Tableau Workbook (.twb) file along with any data extract (.tde) and any other external files (such as images, or Text/Excel files for data sources that are not extracted).
