Having an FTP server in our device is very useful to access the files that we have stored in it and copy them to our computer, delete them from the device or copy new files to the memory easily, remotely and without the need to use No additional software for this purpose other than the server in question.
One of the most powerful yet simple tools to use to create an FTP server on our device is FTP Server Ultimate. We can download this application for free to our smartphone from the Play Store .
Once downloaded and installed, we execute it and we will see the main window of the program, usually empty. The first thing we must do is create the server in question. To do this, click on the + button and the different servers that we can create will appear.
In our case we are going to create an SFTP server, which is similar to FTP but which uses secure SSH connections to protect our traffic and prevent anyone from accessing it. Next, the server configuration window will open.
In it we are going to introduce the name that we want to give to our FTP connection and the port that we are going to use. We can configure the name we want and change the port for the one that best suits us.
The rest of options (for example the use of digital certificates for the beginning of session) are oriented to advanced users so it is advisable not to modify them and leave them in their default values).
The next thing we need to do is click on the "Users" section at the top to create the users that will be able to connect to our FTP.
Click on the + button and a window like the following will appear.
Here we must enter the username and password of who is going to log in to our device and press the back key of our smartphone to exit the user creation menu.
To finish we will go back to the Settings tab and press the back key again to exit the creation menu of a new FTP connection and save the changes.
Our FTP connection through the SFTP protocol is ready to be used.
The only thing left for us to do is run an FTP client on our computer, enter the IP of our device, the selected port, the user and the password, and the connection will be established.
We can now access all the files stored on our device through the local network without the need for cables safely.
