Here is a test case:
We have a table:

CREATE TABLE `sbtest1` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`k` int(10) unsigned NOT NULL DEFAULT '0',
`c` char(120) NOT NULL DEFAULT '',
`pad` char(60) NOT NULL DEFAULT '',
PRIMARY KEY (`id`),
KEY `k_1` (`k`)
) ENGINE=InnoDB AUTO_INCREMENT=2427738 DEFAULT CHARSET=latin1 COMPRESSION='lz4'

mysql> optimize table sbtest1;

[root@ps-5 mysql]# ls -l dbtest/
