Duplicate File Finder is a small, simple, easy-to-use and powerful duplicate file finding program developed by Ashisoft. It can help users quickly find and delete various duplicate files (duplicate videos, duplicate music, duplicate pictures, duplicate documents, etc.) from their hard drives, so as to effectively free up disk space and improve computer performance.

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.

When you use your computer to video chat with others, you may encounter awkward situations where the camera doesn't work, isn't clear enough, can't adjust its angle, or even doesn't have a camera. In such cases, you can connect and use your phone's camera for video calls via some software. Even with an old phone, its clarity is far better than almost any built-in or external HD camera. Better yet, you can also adjust its position and viewing angle at will.

Advanced computer users may install and use both Windows and Linux systems on the same computer. In this case, one of the major problems they face is file sharing between the two systems. In Linux system, you can easily access any file system under Windows by default. But on the other hand, you cannot access/display any file system under Linux in Windows system. Instead, you have to ask some third party software for help.
