Tableau Prep temp files increase in size and cause slow performance. 


  • Tableau Prep 2019.1.3
  • Windows 10
  • MS SQL Server


Option 1:  Upgrade Prep to version 2019.2.2 or newer

In version 2019.2 and newer, Prep now properly removes temp files once they are no longer in use. 

See "Resolved Issues" here: Tableau Prep Builder 2019.2.2

Option 2: Delete temp files manually

With Prep closed, remove the temp files from the following folders:
  • C:\Users\<user>\AppData\Roaming\Tableau Prep Builder 2019.1.3\Cache
  • C:\Users\<user>\AppData\Roaming\Tableau Prep Builder 2019.1.3\GPUCache


This is a known issue that is fixed in more recent version of Tableau Prep Builder.
