Common junk files in Windows OS
No matter how much storage space your Windows machine has, it will ultimately run out. Because there are so many items to download on the internet, many users quickly fill up their hard drive space. What's worse is that, in most situations, what makes your disk slow are all the junk files accumulated in daily use.
▶ Cache files
Cached data is used to load an app or website fast for each subsequent visit because cache stores files, pictures, and other relevant data on your device when you access an app or website for the first time. In fact, it may be found not only in applications but also in software and hardware such as the CPU (RAM Cache).
▶ Temporary system files
When you turn on or off your computer, system files are created and saved in order to activate or shut down certain critical functions or programs. System garbage files become outdated when they have completed their purpose. However, they won't be cleaned automatically.
▶ Installer files
These files are created to help you install programs and apps on your device. These files become obsolete once the installation is complete. Furthermore, certain apps may include additional infections.
Thumbnails can help a photo load faster if you need them again, but most of the time you will only use them once or you will wait a long time before returning the same image. When you revisit the image, a fresh thumbnail is always created.
