How to Delete Unnecessary Files in Windows 10?
Common types of unnecessary files
Windows, the world's most popular operating system, has its flaws, including a large number of unnecessary files and directories that take up valuable space on your computer. While some are essential for the system's functioning, many are redundant and can cause your PC to slow down, lag, freeze, or even crash by consuming space and resources.
To keep your Windows PC running smoothly, it's essential to delete unnecessary files. But, many users are unsure about which files can be safely deleted. Here's a list of files that can be deleted:
• The Temp Folder
• The Hibernation File
• The Recycle Bin
• Downloaded Program Files
• The Windows Old Folder Files
• Windows Update Folder
• Cache files
• Installer files
• Thumbnail
…
Some files stored in system data folders on the C drive cause the C drive space to disappear quickly, leaving users unsure if they can delete them from the C drive. To resolve this, cleaning unnecessary files from Windows 10 is necessary.
How do delete unnecessary files on Windows 10 computer?
1. Use Disk Cleanup
Step 1. Type "disk cleanup" in the search box on the taskbar, and select Disk Cleanup from the list of results.
Step 2. Select the drive you want to clean up (like C drive), and then select "OK".
Step 3. Under "Files to delete", select the file you want to get rid of, and click "OK".
You can also click "Clean up system files" to remove unnecessary system files, but be cautious not to delete important data.
2. Delete Temp files in File Explorer
The Temp folder on Windows is often cluttered with unnecessary files, and while Disk Cleanup can help, it may not always remove everything. To ensure the folder remains clean, it's recommended to manually clear it out regularly.
3. Clean Hibernation files
The Hibernation File, also known as hiberfil.sys, is a large file that stores a snapshot of your computer's RAM when you put it in hibernation mode, which saves all open work to the hard disk, taking up a significant amount of hard drive space, typically a few gigabytes or more, proportional to the amount of RAM installed.
To disable hibernation mode, open the Command Prompt as an administrator, type "powercfg -h off" and press Enter. This will disable hibernation, freeing up hard disk space equivalent to your RAM. However, be aware that disabling hibernation will cause Windows to rebuild the hibernation file from scratch if you enable it again, which can take some time.
Step 1. Go to the Start menu, type "cmd" right-click on the results Command Prompt and select Run as administrator.
Step 2. Then type "powercfg.exe / hibernate off" and press Enter.
4. Clean Recycle bin
After deleting a file or folder, it doesn't disappear completely - it moves to the Recycle Bin, a holding area where deleted items are stored until they're permanently removed or restored. To free up space, it's essential to regularly check and clear the bin, as it can accumulate outdated data, taking up several gigabytes of storage.
5. Delete downloaded program Files
The Downloaded Program Files folder on Windows is often misunderstood. It doesn't contain downloaded apps, but rather stores files needed by Internet Explorer's ActiveX controls and Java applets, so you don't have to download them twice if you use the same feature on a website.
The folder in question is essentially taking up unnecessary space and contains outdated technologies like Java applets and ActiveX, which pose security risks. You can verify the contents of the folder and delete any large files or unnecessary items to free up space.
6. Clean Windows.Old Folder
After upgrading to a new version of Windows, a Windows.old folder is created on the C drive, containing a duplicate of all files from the previous version, allowing for easy reverting if needed.
If you're certain you don't need them, remove them under Disk Cleanup > Clean up system files. If you're unsure, you can also check the system file's properties to see if it's being used by any running program.
