How to Make a Secure Connection (FTPS and SFTP) in FileZilla?

FileZilla supports FTPS (FTP Secure) and SFTP (SSH File Transfer Protocol) protocols for secure file transfer. These protocols ensure that data is transferred in encrypted form and prevent unauthorized access.

2. Create a New Site or Edit an Existing Site: You can create a new site or edit an existing site.
3. Select Protocol: Select "FTP - File Transfer Protocol over SSL/TLS (FTPS)" from the "Protocol" drop-down menu.
4. Configure Encryption Setting: Select an appropriate encryption option from the "Encryption" drop-down menu. Options such as "Require explicit FTP over TLS" or "Require implicit FTP over TLS" are available. You need to select the encryption method supported by your server.
5. Enter Connection Information: Enter information such as Server (Host), Port, Username, Password.
6. Click the Connect Button: After entering the information, click the "Connect" button.

SFTP Connection:

1. Open Site Manager: From the "File" menu, select "Site Manager".
2. Create a New Site or Edit an Existing One: You can create a new site or edit an existing one.
