Sorry, I should have been more clear above.
13.1 has the SQL File field but in 13.1, it doesn’t support variables like %folder%.
I added variable support to the next 13.2 beta, which should come out later today. So if you get the Toad for Oracle 13.2 Beta, after today’s update, then what I described above should work.
We’ll post an update here https://forums.toadworld.com/c/toad-for-oracle-beta when today’s beta update is released.
