Disk Space Saver is an application (or website) designed to help users manage their disk space by finding and deleting unnecessary and duplicate files, cleaning up unnecessary system files, and optimizing disk performance. It can be used to free up disk space by uninstalling unnecessary applications, deleting temporary files and logs, and defragmenting the disk. It can also be used to scan and clean up empty folders, detect and remove malicious software, and optimize the system registry. Disk Space Saver can also help users find and delete duplicate files, which can be a major source of wasted disk space. The app can also be used to back up and restore important system files, giving users more control over their disk usage.
So useful that I use it all the time and recommend it to my friends. The space is very well represented and visualized.
