Hi Clyde Schechter,

No need to apologize for that! It's bad enough that you're taking the time to help me, and I'm extremely grateful!

Thank you for your feedback. I'll see if it works. Once again, thank you for everything I've learned on this thread with you!

Have a nice day.
Michael

Hi again Clyde Schechter,

I confirm thereby that your code works exactly as I wanted. Thank you so much for your help!
Deeply grateful.

In fact, the memory was unable to store all those huge temporary files, but I managed to do it by chunks: Firstly for 2021, secondly for 2022 and thirdly for 2023. Finally, I appended them together.

Lovely day.
Michael
