This week, Apple posted a tip about using FTP directly
from Finder. What Apple fails to mention in its tip is that whenever you connect via the Finder's Go -> Connect to Server option, make sure to include the user name in the ftp address. Don't connect to ftp://foo.org, instead, connect to ftp://email@example.com. Adding the user name fixes nearly all the connection problems that people write to me about. Instead of getting "The Finder cannot complete the operation because some data in (address) could not be read or written. (Error code -36)." an authentication window appears.Update:
Apple appears to have removed the tip page. Interesting.
Update 2: Apple's tip is still live here. (Thanks Francis.)
