Synch - What to do?

Hi,

I have set up a number of 'Synch' profles betweem my Main PC and my laptop.
All Ok so far.

However, one of them is a 'Synch' to all my CD Rips and that is a BIG
'Synch'...

Questions:

1. I assume that the 'Synch' replicates the files on the laptop and then
copies back any changes and updates? - That means I sort of have a full copy
of 700 CD's on my laptop...space could be a problem.
2. How can I delete that particular 'Synch' profile...I do not sem to be
able to find any command to delete that profile, other than asking it not to
update?

All help appreciated.

Regards
