With the development of network technology, our demand for file synchronization and backup is also becoming stronger. While various web disk services provide us with convenience, they also bring a lot of restrictions and risks in terms of speed, security and privacy. There are many cloud synchronization solutions, such as Seafile and Nextcloud, which are feature-rich but bulky and difficult to deploy cloud disk programs. But if we only need to synchronize files, then a better choice is Syncthing. In comparison, it is lighter, easier to deploy and use, more secure, and especially has faster file transfer.

DSynchronize is a classic, small, and free file synchronization tool, developed by Dimio Software from Italy.

For important data, we usually store them on hard disks, optical discs, memory cards and other storage devices. However, once the storage device is damaged, files in it may not be opened or read. At this point, we need to use data recovery software to save as much data as possible. There are a lot of excellent data recovery software for hard disks and so on, but for optical discs you can try IsoBuster first.
