Invisible files on Mac OS X

[Steven]

I'm using Limewire for Mac OS X. It worked fine, until I moved all
the Limewire files into a seperate folder. (after unpacking the
compressed file, all Limewire files and folders are installed in the
downloads folder and not in their own separate folder)
I forgot to reset the preferences for the incomplete en shared
folder. This resulted in that the files that were subsequently
downloaded disapeared. It turned out that there where put in the
Private folder as invisible files. I have no idea how to recover the
files / make them visible again.
