When you work with Tableau Desktop 9.0 and later, your My Tableau Repository might contain a folder called Shadow Extracts. By default, the Shadow Extracts folder can contain up to five shadow extract files, which have a .ttde extension.

The contents of the Shadow Extracts folder change depending on the workbook you work with, and shadow extract files are only created when you work with workbooks that are based on non-legacy Excel or text, or statistical files.

Tableau creates and saves a shadow extract file in order to load your data more quickly. After Tableau creates five shadow extract files, Tableau deletes the oldest shadow extract file to create space when it adds a new one.

Although shadow extract files contain underlying data and other information similar to the standard Tableau extract, shadow extract files are saved in a different format, which means that they cannot be used the same way Tableau extracts are.
