Windows cannot find ‘ ftp://username:[email protected]’. Check the spelling and try again

If any of these special characters # ? / \ % are present in the username or the password, you will get that error message.

KB969869 states that this behavior is by design!

What you will have to do is, encode the special characters in the following way:

as %3A ? as %3F \ as %5C % as %25

as %23

/ as %2F When you do this, you will be able to successfully access the FTP server!
