- To create a .twb file, from Tableau Desktop, select File > Save
2. Tableau Packaged Workbook (.twbx):

The
primary reason you would save your work as a Packaged Workbook is so that you
can share it with other Tableau Desktop users, or for others to open using Tableau
Reader.
- To create a .twbx file, from Tableau Desktop, select File > Save As and then select the .twbx option from the dropdown menu at the bottom of the Save As dialogue box.
3. Tableau Datasource (.tds):

Tableau is clever enough to pick up new columns/fields in the data source if they appear and column ordering does not matter but if column names change or disappear completely, you will need to reconfigure.
- To create a .tds file, from Tableau Desktop, right click on your data source connection and select Add to Saved Data Sources. Alternatively you can publish the .tds to Tableau Server by right clicking and selecting Publish to Server instead.
4.Tableau Data Extract (.tde):
.tde Tableau Data Extracts are highly optimised, highly compressed, subsets of your data stored in a columnar database file. When you connect to data using Tableau you can either connect ‘Live’ or you can extract the data into a .tde. Data extracts are used to radically improve performance, particularly when connecting to slow databases or slow files (e.g. CSVs), as well as enabling additional functionality (try doing a count distinct whilst connected live to Excel) and offline analysis.
You can also use extracts to perform some pre-aggregation of your data, and it can stop load / contention problems that may arise if you are connecting live to a database. You’ll also HAVE to use an extract if you want to publish to Tableau Public.
The primary disadvantage to using an extract is that your Tableau viz is no longer pointing to the ‘live’ data source – if that data source updates then your viz will not until you refresh the extract. Fortunately refreshing an extract is only a few clicks away, or you can set up your Tableau Server to refresh the extract on a schedule.
- To create a .tde file, when you first connect to data, chose the Import all data or the Import some data option. If you are already connected live, right click on your data source connection and select Extract Data.

You would create this type of file instead of a .tds if you wanted to share the connection information with someone else who did not have access to the underlying data (for example if it was stored on your local machine)
- To create a . tdsx file, from the Add to Saved Data Source dialogue box, change the file type from the dropdown at the bottom.

- To create a .tbm file, click Window > Bookmark > Create Bookmark. To reuse a bookmark, clcik Window > [bookmark name]. Note that you cannot create a bookmark from a dashboard page.
7.Tableau Map Source(.tms):

- To create a .tms file, click on Map > Background Maps > WMS Servers and from the WMS Server Connections dialogue window, select Export. If you want this mapping source to always be available to your workbooks, add the .tms file to your Mapsources directory within My Tableau Repository.
