The temp files from Tableau Prep Builder flows are stored in [C:\users\<user>\AppData\Local\Temp] with a name like [prep-<code>].
Normally these files are deleted when Tableau Prep closes down. However, these files survive automatic deletion, when Prep is closed abnormally or using Task Administrator. In cases like that, it is safe to delete them to reduce the size of the Temp folder.
