DirEqual is a file management application designed to help users compare directory structures (folders and files) on their computer. It can compare two folders side-by-side and display any differences, such as missing files, extra files, and differences in file sizes. It can also synchronize folders, which will copy files from one side to the other to make them equal. DirEqual also features a powerful search engine, allowing users to quickly locate files they may be searching for. Finally, it can generate reports that show differences between two folders in a clear, easy-to-read format.
Not available Since October 2013: the latest version, 4.2.0, can still be downloaded from the official website.
