Over the time, your operating system tends to generate temporary files which get on accumulating in the temporary directories. This negatively affects the system responsiveness & off-course wastes disk space. Further, there are also other resources like browser caches, thumbnail caches & more which if not cleared from time to time make the system sluggish. An advance user may very well take control & go rectifying each of the above problems. However that would mean more time to clear up each individual thing. Here, steps in to rescue is KDE’s very own utility – Sweeper(Application>Utilities>Sweeper).
As the name suggests, Sweeper is a tiny utility which lets one clear all the unwanted clutter from the system. The interface of sweeper is ridiculously idiot-proof & all the options are self explanatory. Simply check whatever you wish to get rid off from your system & hit “Clean Up”. Sweeper is capable of clearing cookies, temporary files, thumbnail cache, browser cache, favicons, clipboard, recently used document list, recent applications etc.
From time to time, I recommend running Sweeper & letting it do its job. It will ensure you good disk resources & a responsive computer.
