How to find out what's taking up space on a C drive? Using "File Explorer" with the "Sort by Size" option is an effective way to identify the files and folders that are taking up space on your Windows PC. This method is particularly useful if you want to free up space and improve your computer's performance.

To use this method, open File Explorer and navigate to your C drive. Once on the C drive, click on the "View" tab in the top navigation menu. From the "View" tab, select "Sort by" and then choose "Size." This will organize your files from largest to smallest, making it easy to see which files and folders are consuming the most storage.

By using the "Sort by Size" option, you can quickly find out what's taking up space on a C drive, allowing you to make informed decisions about which files to delete or move to free up storage. This can help you optimize your PC's storage and performance, ensuring that your computer runs smoothly and efficiently.
