When you develop new extension for Joomla, you always do installation and un-installation again & again until your extension works correctly.This work is so boring, so we have developed this extension (based on Joomla installation) to help developers updating an extension without un-installing it. PS Joom Updater also help to drop or backup tables of the extension for new installation in order to reuse old data.

Another reason is almost of Joomla extension producers often "forget" to release an upgrade/or patch version, they often release new version only (without changing the xml file to upragde mode) and some Joomla users don't know how to change the xml file for upgrading new version.
So this component will help Joomla users the easy way to update/upgrade/patch new version for any extensions (component/module/plugin/template).

There are 3 options to choose:
1. Update source code of the extension only
2. Update + Drop old tables of the extension
3. Update + Backup old tables of the extension

Hope you can save much time with PS Joom Updater.
