FTP FileZilla This server does not support over TSL - what is it?

Question

FTP

Hello guys,
I created an FTP server on my phone. I can connect to it, but it says:
This server does not support over TSL. If you continue, your password and files will be sent in clear over the internet (which means my files will be sent over the internet). What does this mean? Is it safe?

Answer 1

The server does not support encrypted connections. The data will be transmitted over the network in clear text. For the local network is not critical.

Answer 2

The server does not support encryption. Or it's not included. Or not configured.
FTP passwords will be sent in plain text.
Anyone who can sniff your traffic can get it -
anyone on public wifi networks for example.
