Sometimes you need a picture or video from your phone and it is too large to send via email, uploading these files to online services can also take quite some time, so why not use your local network speeds to transfer the file to your computer?
In the play store you can find multiple apps such as Solid Explorer FTP Server that can create a ftp server on your android phone that is addressable via FTP (File Transfer Protocol).
2. Make sure you are connected to the same WiFi network as the other device you want to send the data to.
3. press the start button to start a FTP server on your android device.
4. Enter the server address in the windows explorer address bar, (not internet explorer, but the file and folder viewer of windows) and press "enter"
5. you will now see all files and folders saved on your android device, when you copy a file and paste it on your desktop the file transfer starts.
