Hello how are you today?

We have just implemented SAP in our environment. We were finding out that one of our tablespaces on our XI database kept on growing. To accommodate the growth we kept on adding datafiles. We went from 4 datafiles to 20 datafiles on drive G:\ORACLE\PXI\SAPDATA1 and 2 datafiles on N:\ORACLE\PXI\SAPDATA2. Our database is now at 150,000.00 Mb
Just recently we were able to run some delete jobs supplied from SAP. We were able to get all our datafiles under 20% used.

We now would like to delete all our datafiles and reclaim all our disk space.
What is the best way of doing this??

Can you please provide procedures on suggested ideas.

Thank you for your time.

Sorry what I was trying to say is delete the extra datafiles added accept for the 4 original ones.

I'd suggest to drop the tablespace including the datafiles and then recreate it.
drop tablespace TABLESPACE_NAME including contents and datafiles;
