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.

For mobile file managers, if you don't like the old UI of the classic Root Explorer or the bad usability of ES File Explorer, you can give Solid Explorer a try. Compared to similar products, its user interface is more modern and it's more feature-rich than its peers. If you feel that its features are not enough or its UI is not what you want, you can also extend it with plug-ins and icons pack.

In the first place, only the users who have lost data can deeply experience and realize the importance and necessity of backuping data on a regular basis. And the data backup software have been so inundant that we have almost no chance to verify and compare them one by one, so that we can pick out the best one. However, I suggest you put AOMEI Backupper at the top of the list of the data backup software you're going to test.
