Tramp Caches Folder Contents

[Ed Martin]

Hi,
	When using tramp in emacs I sometimes end up adding files to the folder 
I'm working in and tab auto-complete no longer works for those files, is 
there a way to force tramp to re-read the folder contents without having 
to close the connection/files that I'm already using? I can't seem to 
find any way to do that
