Why do I get a 550 FTP error with Filezilla, but IE6 is fine?

"I guess you were transferring the files in IE6 using HTTP? An image with a URL like www.example.com/dir/file.jpg is not likely to be stored in the /dir folder in the root of the file system.

If the home folder of the FTP account is the directory that holds the web site document, then you could try without the leading slash.

If you were using IE6 as an FTP client, then the only thing I can think of: spaces in the file name? Or maybe a different setting in Active/Passive FTP, though then the error message is quite stupid, and it should then happen for all files.

(Any success in IE6 is no excuse not to uninstall it.)"
