The Null FTP Client is currently one of the only FTP clients which takes advantage of a 64-bit Windows platform. Luckily, there are two versions available and one of them is completely freeware.
The FTP client currently supports many of the typical features one should expect from a commercial FTP client, though without registering and thus continuing using the freeware version, you're limit to the amount of connections and some of the featurs you may use.
Unfortunately, if you just want a native 64-bit FTP client, Null FTP doesn't really provide anything more than other, more popular clients. Running as a native 64-bit application under Windows is one of the only benefits.Null FTP Client features and highlights:
Null FTP Client is licensed as freeware for the Windows (32-bit and 64-bit) operating system / platform from ftp clients without restrictions. Null FTP Client 1.0.7 is available to all software users as a free download (Freeware).
