Can you just search a little bit? This has already been posted at least several hundred times.

And do NOT post your title in UPPER case.

Hi,

SELECT SUBSTR (df.NAME, 1, 40) file_name, df.bytes / 1024 / 1024 allocated_mb,
((df.bytes / 1024 / 1024) - NVL (SUM (dfs.bytes) / 1024 / 1024, 0))
used_mb,
NVL (SUM (dfs.bytes) / 1024 / 1024, 0) free_space_mb
FROM v$datafile df, dba_free_space dfs
WHERE df.file# = dfs.file_id(+)
GROUP BY dfs.file_id, df.NAME, df.file#, df.bytes
ORDER BY file_name;

Regards
Sathish

Didn't work is meaningless.
You should post what you found and tried as required in the forum guide.
And if you didn't find the query that has been posted then you didn't search very well.
