List of deletable SAP system files

Our SAP file system is filling up because initially it was defied too small. What are the non-required files that can be deleted from the SAP system? We are using HP-UX NetWeaver2004s on an Oracle database.
The files that can be deleted are mentioned below.

  1. Offline Redo log files
    Backup them and then delete
  2. Old spool and log files
    They are not necessary for R/3 functions and should be deleted regularly by scheduling a periodic batch job.
  3. File name "CORE" (Unix only)
    The R/3 System work directory (e.g. /usr/sap/c11/D00/work ) often contains a file called 'core' from previous program terminations. This file may be deleted at any time.
  4. Old ABAP/4 trace files.
    Use Transaction SE30 to delete the files
  5. Old output requests
    They are stored on the data directory as files SP*.

Remember that deleting these files is not a permanent solution. You should increase the file system sizes.
