WinSCP

This has improved productivity for me. Great tool.

I use this to transfer files to and from my main computer via SSH. Great commander-style file navigation and easy to set up.

Like other people, I use it to access my jailbroken iPod Touch 3G. Would love a nicer looking interface, though.

This has made my life a thousand times easier. No more moving or copying through command line, just open this program up, and drag and drop!

Portable version works flawlessly, and where a couple other FTP clients with the same EXACT settings wouldn't connect with my iPod touch, this one does. Although I'd like to solve that mystery, I'll just accept the fact that this works flawlessly. =D

One of the best open source FTP software. I prefer it over FileZilla because it has better synchronization capabilities.

for iPod Touch Jailbroken goodness

ok, but not better then filezilla..

the best for secure ftp, one of the most used tools in my work

I like the portable version, except for the lack of drag and drop.

A really awesome SCP/SFTP client, if not the best.

Lol, wakoopa-tracker picked this up while I was running it in wine. Cool SCP client, I keep a portable version of it in a TrueCrypt volume.

A great free SCP client. There is even a nice command line function.

WinSCP is a great tool for al who need to transfer files from a windows to a linux machine that has scp or sftp enabled. It can handle with multiple profiles and putty-ssh-keys, so its really great.

If you like to be able to simply drag and drop between windows explorer folders and programs this is the program. In fact, even if you like the standard dual pane local/remote setup it's there as well. A Must Have for anyone who goes back and forth between Mac (and is used to the simplicity of Cyberduck)and PC. The security connectivity features which it is named for are excellent.

Best of all, it can easily be used as a portable ftp client.
