any supporting local file data and background images. This format is the best way to
package your work for sharing with others who don’t have access to the original data.

are a local copy of a subset or entire data that you can use to share data, work offline,
and improve database performance.
Data Source (.tds) – Tableau data source files have the .tds file extension. Data source
files are shortcuts for quickly connecting to the original data that you use often. Data
source files do not contain the actual data but rather the information necessary to

data such as changing default properties, creating calculated fields, adding groups, and
so on.
Packaged Data Source (.tdsx) – Tableau packaged data source files have the .tdsx
file extension. A packaged data source is a zip file that contains the data source file (.tds)
described above as well as any local file data such as Extract files (.tde), text files, Excel
files, Access files, and local cube files. Use this format to create a single file that you can
then share with others who may not have access to the original data stored locally on
your computer.
