TIPS(20) : Make a Map of Your Oracle Files
==========================================
The script below generates a report on all the Oracle files
(database, redo log, and control) in an Oracle UNIX system.
It's like a map of your Oracle files. Moreover, it also makes available other
information (size and physical I/Os, if applicable) related to the files.
THE SCRIPT
rem
rem File: filemap.sql
rem
rem This script provides information on the location/path, file name,
rem size and physical I/Os (if applicable) of all the Oracle files
rem (database, control and redo log) in an Oracle/UNIX platform.
rem

col path format a20 heading 'Path'

col fsize format 999b heading 'M bytes'
col pr format 999999b heading 'Phy. Reads'
col pw format 999999b heading 'Phy. Writes'

Thanks for your reply, but I'm not sure if you understood my point correctly.
I didn't exactly mean to use my iPod as a USB memory stick.
What I meant was that if I copied the contents of my iPod to a DVD and if something weird happened to my music player and I would have to format it...
Could I then just copy the files (I had burned on the DVD) back to my iPod and it would be the same as before? My music would be saved?
