Running out of space on a PC can be frustrating, especially with rising storage and RAM prices. Windows 11 offers a file compression feature that allows users to compress files on their drives, freeing up space without compromising usability. This NTFS compression operates in the background, enabling access to files without manual extraction. To enable it, users can right-click on a drive in File Explorer, select Properties, and choose the compression option if the drive uses the NTFS file system. The compression process may take time, as seen when it took about two hours to compress 333GB of data. While drive compression can consume CPU resources and slightly increase loading times, the impact is minimal on modern computers. Users can also selectively compress specific files or folders to manage performance better.
