Re: autoextent fo data files

Hi,
Check for sys.filext$ ,dba_data_files and v$datafile

There is a column
 create_bytes in v$datafile ( size of file when created) bytes:------gives the current size.

The increment_by column in dba_data_files will give the size by which the data file is incremented.

          hope this helps.
