What are Junk files?

Junk files are temporary files created by your computer to perform and carry out specific tasks. Once their purpose is fulfilled, they become useless. They’re nothing more than useless files taking up space in your computer and negatively affecting their performance.

Having junk files on your computer isn’t your fault; they are inevitable when doing tasks such as downloading a file or opening a document. The good thing is that they’re not as dangerous as viruses, but if they get stored in the computer for too long, they affect its performance which can cause a hindrance to your workflow.

Your System must create a temporary file no matter what you’re doing on your computer. It’s good practice to regularly declutter and clean your PC, browser, and cookies for the best user experience and excellent performance.

The Main Types of Junk Files

All the junk files in your computer get created for different purposes. The files created using Microsoft Word are other than those made when downloading a file or using a web browser. There are specific junk files more common than others. Here are the most common ones:

Downloaded program files:

Downloaded program files are created when installing a program or software on your device. They are needed initially to get the program running but not after its installation. Downloaded file types include a wide range of file types from photos, videos, music, documents and software installations. Downloaded files are necessary, but can accumulate junk files over time. Downloaded files are often stored in the Downloads file on your computer, but can end up in other drives as well, depending on the settings you have set.

Downloaded program files:

Recycle bin files:

Even when you delete them, they still get saved in the Recycle bin. You may need to retrieve the file you deleted, so that’s why the Recycle bin exists. However, the files remain stored on the device until you permanently delete them from the Recycle bin. The Recycle Bin acts as a safety net, since you can restore the deleted files if you need them.

Temporary system files:

These files make essential features and functionality work within your System. Once the work is complete, they become obsolete. These files act as temporary placeholders for software installations, and other downloads. They also include temporary backup files when you’re backing up files on the system. Another part of it are crash dump files that are created when a program crashes. These files can help figure out the cause of the crash.

Thumbnails:

When you go to websites with images, your computer saves thumbnail files so that the images can load faster. They provide quick access to images and media files. Deleting thumbnails can slow the image loading speed, but you don’t need thumbnails once you’re done viewing the picture and no longer need it. Thumbnails are usually stored in a cache folder in your system.
