Deleting unwanted files in your Windows 10/11 computer plays a significant role in increasing efficiency. The term "unwanted files" refers to those files that occupy extra computer space and need to be cleaned up to allow your PC to run more smoothly. Such files may include videos, photos, documents, audios, archives, etc.

When you realize that your storage is running low, it's wise to remove unwanted files, which is a good way to free up space on your computer. In addition, removing unwanted files helps to speed up your system. Duplicate files always slow down computers hence affecting the running of regular programs. To make things better, removing unwanted files also helps remove potential malware from your computer. Viruses may attach themselves to your computer, slowing down most activities (including the basic ones). This article will outline some effective methods to remove unwanted files from the C drive in your Windows 10/11 computer.   

What Files Are Unwanted

Unwanted files are those which you no longer need on your computer. Most of these files are significant for a short period and become irrelevant with time. You may pay little attention to these files at first, but when you find that your computer runs very slow and comes across other issues, it costs you much time to search and remove those unwanted files. Common unwanted files in your computer include the following types:

Duplicate files: These files are usually created when running different applications or performing specific tasks. In addition, the duplicates can be easily generated when you are editing a document, excel, PPT, photo, etc.

Windows upgrade log files: Windows creates some log files when making updates. These files only help with troubleshooting problems during the upgrade process and nothing more.

Thumbnails: Thumbnails help load image or video previews on your computer. However, their thumbnails may remain when you delete the images or videos.

Software leftovers: After uninstalling some programs or apps, their temporary files may still be left behind.

Recycle bin files: These include deleted files that remain saved in the recycle bin folder.

Temporary internet files: These are cache files created by your browser.

Since the above files become irrelevant with time, it's wise to delete them and free up space.
