How to Clean Junk Files on Computer – When the storage space of a laptop or computer is too full of various applications and files, the performance of the computer or laptop can decrease.

There are many types of files stored on the computer. One type of file is a junk file that results from all the activities you do on your computer.

For example, when you surf in cyberspace with a browser, it will leave a lot of junk files in the form of browsing history or caches of visited sites.

All these junk files will be stored in the available computer storage space. If there are too many, it will most likely have an effect on computer performance (such as running slower or feeling sluggish in the case of using HDD storage space).

Therefore, to speed up computer performance and keep the system healthy, you must do regular cleaning of junk files.
