Junk files are something that every computer expert recommends to delete on a regular basis.
How junk files created?
Every time you use your computer, different files are created. When you open a document, It creates temporary files that help things run smoothly and automatically back up your work.
When you browse the Internet, your browser downloads temporary Internet files that get pre-loaded whenever you visit the same websites again to make load faster. Even when you power on or shut down your computer, Windows creates temporary system files. All these files are useful, but the problem is that they don't get deleted automatically when they are no longer needed by your system or your software. That's how temporary files become junk files.
Why junk files should be deleted?
Junk files sound pretty harmless, but unfortunately that's not the case. If you have too many junk files stored on your computer, they will start sorts of problems. The main problem is that they take up a lot of disk space. If you've never done junk files cleanup, then we are talking about gigabytes of wasted space. And even if you run disk cleanup occasionally or have a relatively new computer, you may still have one or two gigabytes of junk. So, if you start running out of space and especially if you have an SSD, you should run disk cleanup regularly.
Another reason is they make your computer slow. The more outdated temporary files you have, the more time your system needs to find your documents, open programs, launch web pages and so on. And if there are too many junk files on your disk, your computer can get really slow on startup. Deleting junk files not free up valuable disk space, but it will also make your computer faster.
