But the real question arises, "How to remove junk files from PC" as you won't find them all in one place and there isn't a single type of junk file. That's why in this article, we've discussed five ways to purge your Windows 11/10 PC of its junk files, saving space and boosting performance. Without further ado, let's begin!
Part 1. What Are Junk Files?
Junk files refer to unnecessary, no longer needed, or temporary files that accumulate on a computer over time, such as cache files, temporary internet files, system logs, etc. Although they're not harmful like viruses, they are like clutter that you never really use or need. They do clog up your system, take up space for no good reason, and slow down your computer. There are many types of junk files such as:
- Temporary Files - When you browse internet, your browser creates temporary files to speed up page loading. This eats up storage space and fills your hard drive gradually.
- System Cache Files - Windows and other applications create cache files to store frequently accessed data for quicker access. However, these files can accumulate over time and become unnecessary.
- Application Leftovers - When software is uninstalled, some of its corresponding files are left behind. These remnants are unnecessary and can clutter the system if not removed.
- Recycle Bin Files - When you delete files, they move to recycle bin, but they don't vanish on their own. You have to empty recycle bin on your desktop regularly to clear up space on your hard drive.
- Log Files - Windows and applications generate log files to record system events and errors. These files can grow large over time and may no longer serve a useful purpose.
- Large and Duplicate Files - Big files take up a lot of room on your hard drive, so delete ones you don't need. Also, watch out for duplicates. Having multiple copies of same file chews up space fast.
