Your path should contain your root path followed by a slash followed by the
destination folder's name. If you are on a WINDOWS server, each slash should
be escaped. Eg. each seperator should look like this : \\\\
<p>
Sometimes, the root returned is not the full path to your web space. In this case
you should either check with your host or if you are using an FTP client such as
CuteFTP, change to the folder you are trying to upload to and look at the path you
have taken. You can see this just above the list of files on your server.
You must use the same path in the \$dir variable.
