Review on freeFTPd by Will Ridpath

Easy to use, easy to install, works like a charm with all the standard file transfer programs (like FileZilla). The only thing I dislike about it is that you can't set up your own accounts in the program itself. You have to go into the configuration folder and edit every single account. It's not very user friendly, but once you know how to do this, it's pretty simple. Just make sure you have enough space available before you start transferring files. If there isn't enough space left on your drive, then you won't be able to save any more files after you've started uploading them. This has happened to me many times before, so I just keep a backup or two of my documents on another drive.
