I'd love to know this as well...
Did you get the answer for this?
I found that whilst in Team Sync view you can go to the tab "Site Explorer" there you can right click on the connections and edit properties or just delete
Hope that helps
Thant did help, but I must admit that I miss the ability to simply download/upload or synchronize. I find how they have setup CFB 3 cumbersome and not overly intuitive. My solution was to uninstall CFB 3 and the install Eclipse Lunar. I then installed CFB 3 as a plugin and then installed Aptana Studio 3 as a plugin, which through the Aptana App Explorer gives me my FTP transfer options back. I also find CFB 3 is faster and more responsive installed as a plugin.
1) CF Builder 3 does not have native ftp support
2) What I hope you are trying to do is to get FTP Support for CFB3
3) Go To Help/Install New Software/Select from the drop down All Available Sites/
make sure the check is in "Show only software applicable to target environment
In the "type filter text" type "remote", what you are looking for is the "remote system explorer" under general purpose tools
check them both and install
4)Once installed and restarted CFB3 will have muthaf*cking ftp support "proper". Under Export you will see a new option, "Remote System"
from this option you will be able to set up a "proper ftp connection". Saints be praised. Why this is not STOCK for CFB3 is beyond me, but Peace be unto you.
Blessed be the Bandwidth, the internet will provide!
