One of the common tasks the web application might be required to perform, especially the app using some kind of a CMS, is to save the history of data changes. Your client for sure will want the answer to this simple question - If I mess this up or delete by accident can we bring it back? Well, DB backup is one thing and quick recovery is another - let's talk about latter one.
>Info: As KCFinder's documentation mentions, if your application (Yii in our case) session handling is using the PHP environment configuration - meaning no change in session handling at all, then no change is needed also on KCFinder side to be able to use this session and thus have this simple interface between your Yii webapp and KCFinder.
