After Oracle 8i R2 (8.1.6) for NT Enterprise Edition is installed by default, the following three directories are created on the drive letter.
Admin: records the configuration and running logs of Oracle instances. Each instance has a directory.
Ora81: Oracle System File
Oradata: all the specific files (data files, log files, and control files) required for running Oracle instances. Each instance has a directory.
Generally, Oracle files are classified into the following types:
Data File: Real Data
Redo log files: Online logs and archived logs
Control File: contains the ing between physical files and logical tablespace in the data dictionary.
Initialize parameter file: Control Memory
