Before you begin, you will need to download FileZilla and install it.
FileZilla is a free FTP program (also called an FTP client) that allows you to upload, download and change permissions of files you keep in the webspace of your 1&1 package. FTP is insecure in that it transmits your password in plain text. The good news is that FileZilla supports FTPS which you can use to securely transfer your files.
The reference images provided reflect FileZilla 3.5.2 running on a Windows PC.
|Host||The subdomain is found in the 1&1 Control Center|
|Protocol||FTP - File Transfer Protocol|
|Encryption||Require implicit FTP over TLS|
|User||FTP username from the 1&1 Control Panel|
|Password||FTP password set in the 1&1 Control Panel|
You should now be able to connect and begin transferring files. To upload, select files from the left-hand side of the windows and drag them to the right-hand side of the menu. Let go of your mouse button to "drop" the files on the right-hand side to upload them.
