FTP client that supports 2 concurrent FTP sessions

Question

I'm looking for an FTP client that can connect to two different FTP servers at the same time and allow file transfer or synchronization between those two servers. Basically what I want to achieve is to transfer/synchronize files between 2 different sites from my local machine. Are there any clients around that support this functionality? If there are none, is there an alternative to achieve this?

I've taken a look at net2ftp, a web based FTP client, which provides almost the same functionality that I need. What I'm looking for though is a desktop app. Any ideas?

Answer 1

Total Commander allows multiple concurrent FTP sessions.

you can sync/compare files and folder and of course copy/move from one server to another.

Totall Commander is shareware, try before you buy.

Answer 2

You should try FTP Expert, best FTP software ever in my opinion.

It seems it is now called Ace Ftp.

Answer 3

If the servers supports it you can use the File eXchange Protocol (FXP).

FlashFXP supports FXP.

Transmit (Mac OS only) supports multiple concurrent connections and FXP for direct server-to-server transfer. It has a great UI as well.
