For Android developers and hobbyists, the typical approach to file management on an Android device means accessing the device using adb shell and typing Linux shell commands by hand. While this is very efficient for specific tasks, it is a cumbersome way of actually exploring the whole file system of the device.
Like it’s cousin “Process Explorer”, File Explorer offers a graphical file manager interface on Android devices through an ordinary desktop web browser instead of through the device screen. There are plenty of products which offer file management feature through the device screen, which, in the case of Android devices, is often small or might even be absent. Instead of being forced to use a command line, developers now have the choice of using File Explorer which allows them to remotely access the files stored on their device through the familiar interface of a file manager.
