Unable to list remote directory?

Hi there do I have the format correct?

synchronize both F:\Downloads /home/user/downloads/*

also tried
synchronize both F:\Downloads /home/user/downloads - still can't find the directory?

I keep getting this in my log

Error listing directory '/home/user/downloads/*'. ("No such file or directory.

The remote directory definitely exists

Figured it out... remote directory had to be case sensitive... uppercase D
