Wifi FTP Server has just gone on sale for $0.99. This is the first time this app has dropped below its regular price of $1.99. This app allows you to start an FTP server on your Fire TV or Fire TV Stick in order to remotely access files stored on your device. Note that the app only gives access to files stored in the /sdcard directory of your Fire TV. This means it will not allow you to transfer files on or off of a USB drive connected to a Fire TV because those files are located at /storage/extUsb.
