The biggest killer of disk space is duplicate files (such as videos, music, and pictures). Especially all kinds of photos, if they are not sorted and organized during the transfer process, it is easy to generate duplicate files. The result is often many duplicate images exist in one folder or different folders, wasting a lot of disk space. To solve this problem, we can use a tool like PictureEcho to scan and delete duplicate images, thus effectively freeing up disk space.

Due to various reasons, as time goes on, the system has accumulated lots of empty folders which will affect the file finding or managing speed and efficiency more or less. Therefore, we need to remove them. But in order to avoid the trouble of manually finding and deleting, we can use Remove Empty Directories.
