Hi @arkiboys ,
Thank you for posting query in Microsoft Q&A Platform.
As per my understanding asks are, Is data preview shows only partial data? and What Clear folder option will do. Please correct me if my understanding is wrong.
Yes, Data preview option will show only partial data not all the data &
Clear the folder
Determines whether or not the destination folder gets cleared before the data is written.
Hope this helps. Please let us know if anything further queries. Thank you.
