Hey @Ayushi_Suthar, I am talking about the link you shared - click here. It says the following

REPLACE

If specified replaces the table and its content if it already exists. This clause is only supported for Delta Lake tables.

REPLACE preserves the table history.

---

That is why I think that Delta does not delete the files that already exist at the location, in case they might contain the history of the previous version of the table. And since it does not need to delete the data that is already there in the location it can create a managed table without any error. Whereas other formats need to delete the data and produce errors. Am I right?
