After using the "Create Like" feature to create a table or the DDL for the table, the TempDataOutput! directory gets populated with enormously big files. What are these files and why are they so big? Can these be removed?
In general, this folder is used when working with export ddl actions and other situation that deal with scripts and inserts. A users could have done an export ddl action to make the folder. Or these files contain insert statements of the data from the table used in the "Create Like".
The more data the table had, the bigger the file will be. These can be manually removed as long as they are no longer used by any exports or scripts.
