forcing lower case: how do you do it?

That's all I really need to know.... so that whatever file names I'm sending to the server have uniform extinsions such as "jpg" insted of the original "JPG"

1. menu: Favorites->Edit Favorites
2. Locate your favorite. Look in the Quick Connect folder
3. Right-click on the favorite and select Properties from the context menu
4. Go to the Transfer->Auto Rename dialog
