   - In Spark 3.0, you can use `ADD FILE` to add file directories as well.

`true`.
 
-  - In Spark 3.0, `SHOW TBLPROPERTIES` throws `AnalysisException` if the table 
does not exist. In Spark version 2.4 and below, this scenario caused 
`NoSuchTableException`. Also, `SHOW TBLPROPERTIES` on a temporary view causes 
`AnalysisException`. In Spark version 2.4 and below, it returned an empty 
result.
