1) Database Table Clean:
Many plugins do not clean up their database tables after you uninstall them.
What happens most of the time is that the plugin files and folder is deleted but not the corresponding plugin database tables.
This where this plugin comes to the rescue. The WPDBSpringClean plugin identifies unused, WordPress DB tables which have
been left over from old plugins you have uninstalled on your site and it then gives you the option of deleting these tables.
2) Database Table Optimization:
Due to regular insertions and deletions in the various DB tables on your system, these tables can quite often hold allocated but unused space.
Consequently this can make your DB tables inefficient, fragmented and unoptimized.
This plugin will identify unoptimized tables and will allow you to optimize them by deleting the allocated unused space within a particular table.
The plugin also optionally allows you to specify search criteria such as the minimum amount of overhead per table and minimum unused space for a table.
By default if no search criteria is specified, the plugin will identify all tables which have an overhead of greater than 10%.
(Note: “Overhead” in this plugin is defined as (Data_free/Data_length) expressed as a percentage and where Data_free and Data_length are MySQL table parameters)

常見問題集
- Will this plugin prevent me from deleting the wrong table?
-
WPDBSpringClean identifies only those database tables which are considered
not part of any of your installed plugins (either ACTIVE or INACTIVE).
When WPDBSpringClean has finished its query it will list all of the tables it
believes are not being used and it will give you the option of deleting some or all of these tables.(As a matter of prudence it is recommended that you take a DB backup if you are unsure about deleting particular tables)

1.3
- Added new functionality:
WPDBSpringClean now also offers the ability to search for unoptimized DB tables (ie, tables which have a high overhead whereby they have a high percentage of allocated but unused space)
WPDBSpringClean then gives you the option of optimizing these tables so that your database uses its space more efficiently.
