What do you mean?
Are you music files stored in a directory that is separate from where you download to?
In my setup I have a different directory just called My Music in the main C:\ directory.
and the download directory is in a separate place under Users\Robert\music download
A good idea is to read as many of the 'Sticky" posts as you possibly can.
Quite often there is someone else that has suffered the same problem as you have and the talented moderators have come up with a solution.
Unfortunately it looks a lot like you have been scammed. Did you download LimeWire from their official site?
