Accessing your installed SD card from a computer using a micro USB cable isn’t the most convenient solution, as you need a cable and a free USB port, and your smartphone is most likely hidden someplace inconvenient. All these obstacles may significantly increase the time it takes to send over a file or album to your SD card.
If your device is constantly connected to a WiFI network, you can use it as a link between your PC or even other device (not necessary with Android installed) to access it. All you need is an application created by XDA Forum Member DmitriL who created a tool to easily access your device through your favorite web browser. The concept is pretty similar to famous AirDroid.
To use the app, you need to install a client on the Android device and type the IP and port to connect with it. The application automatically generates a PIN code to make the connection safer and protect it from intruders who want to check your files without your permission. With Droid Over WiFi, you can easily upload, download, and modify files and directories. If you have multimedia files on your phone, they can be easily streamed using the browser.
