How can I configure Filezilla to use a SFTP connection?

There are two mechanisms for use of the FileZilla client with SSH2 keys:

1 In the profile settings in the Site Manager of the FileZilla client. If the SFTP Protocol is specified, it is possible to specify the Logon Type as "Key File" and specify the location of the private key file (in .ppk or .pem format - see below for conversion options from other formats.) The user is prompted for the key file's password if necessary, which may optionally be cached by Filezilla until it is next shut down. 2 In the Edit - Settings menu of the FileZilla client, you can [Add key file...] under Connection - SFTP, and FileZilla can then use the public key authentication in the site manager with the 'Interactive' Logontype on connection. Note: Importing a site's public key is not supported.
