Best Windows Computer Junk File Cleaner

Why do you need an all-in-one computer junk file cleaner?

Junk files on a computer refer to various types of temporary, redundant, or unnecessary files that accumulate over time as a result of regular computer usage. These files serve no productive purpose and can often lead to several negative consequences.

Generally, your computer will store these junk files.

Temporary internet files
When you browse the web, your browser stores temporary internet files, including cached images and web pages. While these files speed up page loading, they can consume disk space over time.

System logs
System logs are generated by the operating system and various applications to record events and errors. While these logs are essential for diagnosing issues, they can accumulate and fill up disk space if not regularly managed.

Temporary program files
Many software programs create temporary files during their operation. These files are meant to be deleted after use, but sometimes they remain on the system, taking up space.

Old backups
Backup files are crucial for data recovery, but outdated or redundant backup files can become junk over time, especially when new backups are created without removing the old ones.

Recycle Bin contents
Files deleted by the user are initially moved to the Recycle Bin. If not emptied periodically, the Recycle Bin can accumulate a substantial number of files, consuming space.

We can't say that these files are definitely useless files. They were helpful but not now. That's why Windows don't clean these files automatically. If you don't manually remove them, the menace of junk files can result in the following issues:

Reduced disk space: As junk files accumulate, they can significantly reduce available disk space. This may result in low disk space warnings, making it challenging to store new data or install software.

Slower performance: A cluttered hard drive can lead to slower system performance. It can take longer for your computer to boot, launch applications, and perform tasks.

System instability: Large amounts of junk files can lead to system instability and errors, as they may interfere with the normal functioning of your computer.

Risk of data loss: In some cases, essential files or data may be deleted accidentally when cleaning up junk files. This can lead to data loss if proper precautions are not taken.

Reduced productivity: Sluggish performance can hinder productivity, making tasks take longer than necessary.

To address these issues and prevent the negative consequences of junk files, it's essential to regularly clean up and remove unnecessary files from your computer using tools like disk cleanup utilities or dedicated software, as well as taking precautions not to delete essential files accidentally during the cleanup process.

Opt. 1. Run PC Cleaner to clean junk files

Managing disk space remains a persistent challenge for computer users. "Clean Junk Files" feature provides a solution by conducting a thorough scan of your device and intelligently categorizing unnecessary files for removal. No matter the Cache files, temporary system files, installer files, and Thumbnails, following the scan, you have the option to either initiate a comprehensive cleanup by selecting "Clean All" or tailor the deletion task for specific files, aligning with your preferences.

Step 1. Initiate Clean Junk Files. Install and launch AOMEI Partition Assistant for Cleanup. Click the "Clean Junk Files" tab.

Step 2. Start scan junk files. Click the "Scan Now" button to start the process of scanning junk files.

Step 3. After the scan process is finished. All system junk files (including recycle bin files, temporary files, log files, invalid shortcuts, and so on) and registry junk files (including DLL registry, system registry, and program registry) will be displayed.

Step 4. You can also click the button behind to view the junk files details.

Step 5. And, you can click the button behind to locate the file.

Step 6. Select junk files to start cleanup. By default, the program will select some junk files to clean up, for example, temporary files, log files, and so on. You can also manually check to select more or uncheck to deselect fewer listed junk files. Or, click "Select All" to select all junk files to clean up if you need to clean up all.

After selecting junk files that are not needed anymore, you can click the "Clean Now"button to start the cleanup.

Step 7. Cleanup completed. The process of the cleanup might take time, and the selected files will be cleaned up. After the process is finished, you will get a cleanup completed window displaying how many files you have cleaned and not yet cleaned.

Now, all junk files are removed by this handy tool.

Opt 2. Delete duplicate files safely

The "Duplicate file finder" function is a very useful computer software. When your system has a lot of duplicate files, it needs to go through a lot of them. Manually searching duplicate files in a computer is a time-consuming process. The searching is often paused because File Explorer takes too many resources. So, a handy tool would be a better choice.

Step 1. Initiate Find Duplicate Files. Install and launch AOMEI Partition Assistant for Cleanup. Click the "Find Duplicate Files" tab.

Step 2. Select a path to scan duplicate files. You can either click "Scan Now" to start the scan of your system C: drive. Or, click "Custom Scan" to manually select paths to be scanned. (Here, we take the "Custom Scan" as an example.)

Step 3. After clicking "Custom Scan", all local and external drives on your PC will be displayed. You can also click the "Add Path" button, and then a browse folder window will pop up. So you can add more paths on this PC, like Desktop, Downloads, and other folder paths.

Step 4. Once necessary paths are added, you can click the "Scan Now" button to start the scan process.

Step 5. The scan process might take time. After the scan is complete, all duplicate files will be listed. You can click the button behind to locate them.

Step 6. Select duplicate files to start deletion. You can either manually select duplicate files, or click the "Smart Select" button to automatically select unnecessary duplicate files to delete.

Tips: If the "Smart Select" is ticked, only the oldest duplicate file will be unticked. It means that all duplicate files except the oldest one will be ticked to delete. (The oldest file means the file that was created first. This file will not be deleted. All other duplicate files are considered copies of the oldest file. )

If you manually select all copies of duplicate files, you will get a pop-up warning window to keep at least one copy of the duplicate files. If you indeed want to delete all copies of duplicate files, you can click "OK" so all copies of duplicate files will be selected to delete.  

After unnecessary duplicate files are selected, please click the "Clean Now" button to start the deletion.

Step 7. Delete successfully. The deletion might take time. After the process is finished, the selected files will be deleted, and you will get a cleaning completed window displaying how much data you deleted in total. 

Opt 3. Completely delete large files 

Step 1. Initiate Delete Large Files. Install and launch AOMEI Partition Assistant for Cleanup. Click the "Delete Large Files" tab.

Step 2. Select a path to scan large files. You can either click "Scan System Drive" to start the scan of your system C: drive. Or, click "Custom Scan" to manually select paths to be scanned. (Here, we take the "Custom Scan" as an example.)

Step 3. After clicking "Custom Scan", all local and external drives on your PC and the common Desktop, Documents, and Downloads paths will be displayed. You can manually select paths to be scanned. Once necessary paths are added, you can click the "Scan Now" button to start the scan process.

Step 4. The scan process might take time. After the scan is complete, all large files found will be listed.

Step 5. You can also check the large files and click the button behind to locate them.

Step 6. Select large files to start deletion. Tick the files you want to delete, and then click the "Clean Now" button to start the deletion.

Step 7. Delete successfully. The deletion might take time. After the process is finished, the selected files will be deleted, and you will get a cleaning completed window displaying how much data you deleted in total.
