Abstract - The necessity for seamless file sharing and remote device control has grown in importance intoday's fastpaced digital world. The goal of this project is to close the gap between laptops and mobile devices by introducing a userfriendly Java-based application. Using Java's Socket class, the application enables simple wireless communicationbetween a laptop serving as the server and a mobile device serving as the client. Quick file transfers between devices are possible without the inconvenience of extra storage or physical connections. Additionally, the application gives users the ability to remotely operate their laptops by letting them use their mobile devices as virtual keyboards, mice, and joysticks. This user-friendly interface increases convenience and productivity by giving users a flexible toolkit for interacting with their laptop remotely. The screen sharing feature of the application is essential to its functionality as it enables users to instantly mirror their laptop screens onto their mobile devices. This feature improves flexibility and accessibility, allowing users to work or present from anywhere with ease. It also makes remote monitoring and collaboration easier. This project intends to simplify the interactionbetween laptops and mobile devices by merging file sharing, remote control, and screen sharing features into a unified Java-based client-server architecture. In the end, it provides users with an all-inclusive solution for remote control and wireless file sharing, meeting the changing needs of contemporary digital workflows.
