innodb_file_per_table

[drsystems]

Hi,

I read in
http://dev.mysql.com/doc/refman/5.5/en/innodb-multiple-tablespaces.html
that using the innodb_file_per_table will help to reclaim space when a
mysql database grows too large, even though actual data has been deleted
from it. I am using mysql/innodb with dbmail and need to find a better way
to manage disk space.

My question is: will the command OPTIMIZE TABLE actually shrink the .idb
file?

Thanks,
