Link to Windows is a free app by Microsoft for Android that allows seamless file transfer between Android devices and Windows PCs running Windows 10 or 11. The app utilizes the operating system's built-in share feature and requires both devices to be online. File transfers occur over Wi-Fi by default, but Android users can enable mobile data for cellular transfers. The Phone Link app on PC enables management of certain Android device features, allowing users to browse photos, although it does not support bulk actions. To set up Link to Windows, users must download the app, sign in using a QR code, and grant access to specific features. The setup must be repeated for additional devices.
