How To View Data Files in the Current Database?

If you want to get a list of all tablespaces used in the current database instance, you can use the DBA_TABLESPACES view as shown in the following SQL script example:

SQL> connect SYSTEM/fyicenter
Connected.

SQL> col tablespace_name format a16;
SQL> col file_name format a36;
SQL> SELECT TABLESPACE_NAME, FILE_NAME, BYTES
  2  FROM DBA_DATA_FILES;
TABLESPACE_NAME FILE_NAME                           BYTES
--------------- ------------------------------- ---------
USERS           \ORACLEXE\ORADATA\XE\USERS.DBF  104857600
