i.Ftp is a little graphical FTP/SFTP client, which does what I need in an FTP client without the size and fuss. I originally wrote i.Ftp to be the first freeware graphical client for BeOS, but someone beat me to it by a few days and well nobody notices who comes 2nd.

Source is available so if you want to fix that glaring bug and just tinker with it by all means, hack away. Download Lgi and the source. The projects for building the Win32 version are included, you'll need Visual C++ 6.

i.Ftp also works from portable media like USB keys as it doesn't store anything in the registry and it finds it's resource files via relative paths.A full install is about 900kb so it doesn't eat up much space on your portable storage. If you don't need SFTP support then you can delete libssh.dll and libeay32.dll to make it even smaller!
