Gives you the ability to share & manage files from your windows pc on another device(MAC,LINUX,ANDROID etc) in the same network without needing another application on the receiving(client) end, (the client uses the devices browser to download, or view/modify files). It contains an inbuilt http server hence no need for an application on the receivers end. The host turns on the application and the client opens the browser and types the ip address including the port ( the application automatically generates it, hence no need for ipconifg on cmd or any other ways to get ip), then he has access to all the files on the other pc with a very beautiful interface. the client also has a possibility of watching videos, playing music and images directly on his or her browser without having to download it. Depending on whether there is read write access, the client can move files to other directory, delete multiple files, download multiple files to his/her own device and many other options
