It's only a matter of time before you fill it up, even if your PC installs a TB drive. Slow computer performance is a common outcome of not cleaning your computer for a long time, not to mention lagging or regularly frozen PC.
▶ Common junk files on PC
Besides what you download from the Internet, various data files will be stored on your PC no matter whether you need them or not.
• Temporary system files
System files can be created and saved even you turn on or off your computer. They are used to boot or shut specific critical functions or programs. When system files have served their job, they become obsolete and won’t be not automatically cleared.
• Cache files
A cache is temporary storage space that enables a device, browser, or app to operate more quickly and effectively. After you access an app or website for the first time, a cache saves files, pictures, and other pertinent data on your device. The cached data is then utilized to swiftly load an app or website for each future visit. When you first view a webpage, the information on that page gets cached on your computer. Then you may reopen this page more quickly the next time.
The system cache in Windows is a quick storing technique. It might be a standalone high-speed storage device or a dedicated area of main memory.
• Thumbnails
Thumbnails can assist a photo load faster if you need them again, but most of the time your PC only needs them once or you'll have to wait a long time for the same image to be returned. When you return to the image, a new thumbnail is always generated.
• Program files
Program files are designed to assist you with installing and running application apps on your device. Once the installation is complete, some files become outdated, and there will be a large number of registry files and other data once you boot the applications each time. Furthermore, certain apps may contain further malware.
When these junk files pile up, sorting and filtering through all of your files and applications may be extremely difficult and time-consuming, especially if done manually. PC cleaner tools can assist you in removing old and unneeded files from your computer, therefore increasing its overall performance. They often delete temporary files, items left unused in your Downloads folder, and objects in your Recycle Bin.
Cleaning the computer should become a regular work, otherwise, the computer's performance may suffer. If you are not a deep user, home computers may be cleaned once a year on average, but workplace computers should be cleaned every 1 to 3 months.
Although Windows has some built-in tools to help you clean your computer such as Disk Cleanup, Storage Sense and directly deleting files, these tools can’t thoroughly clean all junk files and you may delete important files by mistake.
In this case, we suggest you choose a third-party PC cleaner. Windows free PC cleaner, AOMEI Partition Assistant for Cleanup, is a disk and partition manager for Windows 11/10/8/8.1/7/XP. Its “PC Cleaner” feature can scan your computer and find all junk files hidden in your disk, then you can select the files to clean or not.
