FTP stands for File Transfer Protocol. It is a network protocol for transferring files between computers across a network, on the internet or in LAN. It is one of the most common ways to transfer files from a local computer to a computer server. For example, many web designers use FTP to upload website files from their computer to hosting server to publish their website online. Generally speaking, you will need an FTP server, a user account, and a client or FTP application in order to transfer files using FTP. Some FTP servers allow users to connect as anonymous users, so no username or password is required. Sometimes a web browser or file manager is used instead of an FTP client.
FTP file transfer on mobile
However, FTP can also be used to transfer files between local computers or any other devices, such as mobile phones, tablets, in the same LAN. In this case, the computer or device hosts the files and data acts as the server, other computers or devices act as the clients. On Mac, you can enable remote login to turn your Mac into an FTP server; on Windows, you can turn on IIS and add FTP site to your PC; some Android phones, notably the Xiaomi and Redmi phones come with the FTP support. And there are plenty of apps on Apple App Store or Google Play that can turn our smartphones into FTP file servers or connect to FTP servers from our mobile devices. Following are some of the free apps with FTP support.

CX File Manager
CX File Explorer is a popular file manager with a clean and intuitive user interface that people can use to manage the files on their Android device, PC, network-attached storage, remote or shared storage, cloud storage, etc.

FTP, USB or Bluetooth
Compared to file sharing through USB or Bluetooth, FTP is easier to setup and much faster to transfer files. You just need to connect all devices or computers to the same Wi-Fi network, or create a hotspot on the phone or computer to use FTP. Please keep in mind this does not mean you need internet connection or valid cellular plan. The local file sharing via FTP copies files between local devices and computer once they are connected to the same Wi-Fi network even if the wireless router is not connected to the Internet, a PC hotspot even if your computer is not connected to Wi-Fi or a mobile hotspot without a data plan.
Setup FTP server on Mac
