how to reduce a file (less then initial size)

Hi,
I have created a database with a 20gb initial size.
but I want to reduce this file
how to do this?
because the shrink command doesn't works.
or maybe I have missed an option?
thanks.

DBCC SHRINKIFLE(<file id>, <target size>)
... Target size, of course, won't go beyond the size of the data in the file
(although you can set it as low as you want -- it won't give you an error
for going too low).

I don't understand why before the shrink has never worked...

How to reclaim DB space?

I have a sql2000 database at almost 25gigs. When i checked the
properties, it says 87% is unused space. When i went into the shrink
menu, database file looks reasonable(around 2gigs), but log file is
17gigs with 2gigs used. So, almost 15gigs free space. How do i reclaim
that space and return it to the NT file system? I also did a backup of
full database and also re-backup the log files. Also tried all kinds
of shrinking switches like truncating, rearranging etc...shrink to
3gigs...it comes back with successful but size remains around 17gigs.
what gives?
thank you.If you don't do regular log backups, set the database to simple recovery mode. As for shrinking of
the physical files, see the links at about the middle of this article:

Have you tried DBCC SHRINKFILE on the log file?

Change the recovery model to simple (found by right
clicking on the database, then going to the options tab).
Then run the following:
backup log <database_name> with truncate_only
go
dbcc shrinkfile (<logical_log_file>, 100)
Note: to get the <ligical_log_file>, run sp_helpfile.
important: This will not cause you to lose any data, BUT
you will not be able to restore using your tx-log backups
anymore (because you just truncated it!). So, make sure
you do a full SQL backup on this database before giving my
script a go.
You can then change the recovery model back to bulk-logged
or Full if you so require.
Enjoy
