Since you are reading this, it's safe to assume, you have a Computer, WiFi and few android phones. Right? And every once in a while you need to send files from computer to Android. For me, I usually transfer big videos likes movies or tv shows. But it can be anything. If this was a few years ago, the only option you would have is to use a USB cable. But not anymore. Now you can easily send or receive files using WiFi. This is quick and easy. All you need is both devices connected under the same WiFi network. This even works with a mobile hotspot. send files with Wifi So which is the best way? Well, there are several ways to transfer files between Computers and Android. I am sure some of you know are already aware of them. However, my favorite ones are Airdroid and ES file explorer. Why? Well because these are quick, easy and reliable. There are two cases to consider. 1. Transfer files from Computer to Android 2. Transfer files from Android and Computer For the first one, we will use Airdroid and for the second we will use ES file explorer. And while we speak of computer, I usually considering PC and Mac. Haven't tried on Linux, but it should work though. Side Note: If you don't want to get 2 separate apps, use only ES file explorer. It can do both i.e. send files between computer and Android and vice versa. Here is a detailed tutorial. However, I introduce Airdroid because it can do much other awesome stuff. We see them later on.

Launch the app and you will see a web address similar to 192.168.1.101:8888, go to your computer and type this on the browser 3. You will see a authentication pop up on your Android. Tap OK, and connection will be establish. Drag and drop the files on to your browser and it will get downloaded to sdcard/Airdroid/upload directory of your Android See the screenshot below.

For instance, you can use your android as a surveillance camera, make calls or send messages or even control your Android screen from the computer.

ES file explorer is the best file manager app. It can do much more than regular file manager app. One of that many feature is file transfer. Follow this steps 1.
