You want to make a copy of your sites.dat and bring that to the other system. Take a copy of the FlashFXP.ini too. They're both in you main FlashFXP directory in your program files. That should be it.

BTW - doing what DD said will lead you directly to the the sites.dat file. The FlashFXP.ini is just settings. If you like the way the program runs for you one machine, you can just overwrite it on the new machine and achieve the same settings without all the dicking around. If you are running two different operating systems, just leave the ini file alone. Could be problematic.
