Every time I get a new device and need to transfer files or installation packages, it always feels very troublesome. When I want to share files with colleagues or friends, especially large files, it's also quite difficult. CrossSend was born to solve these problems. Just install CrossSend on one device, and other devices can transfer files bidirectionally through a browser - secure, convenient, and free from complicated steps. Special tip: If your device and your friend's device are not on the same local network, or if the local network has security restrictions that prevent connections, you can turn on the mobile hotspot on the device with CrossSend installed.
