dba_data_files data file not appears but dbf file in exists on FileSystem

Do NOT  Confuse

If you have executed command "DROP TABLESPACE *** INCLUDING CONTENTS AND DATAFILES;" on oracle database it would be noticeable that table-space and data-files has been deleted from server metadata i.e. no entry can be seen in dba_tablespaces and dba_data_files object.

But if you move to data-file physical path on your machine (in which oracle is installed) you may able to see old data-files (do not worry)!!.

Now you are thinking that i have deleted table-space why these files are here or you would try to delete this manually.

Is it safe to do? , can you delete this manually?

Yes you can delete this manually
1. Stop the server
2. Restart the Server
3. Delete unwanted datafiles from physical location
