You need to know which folder(s) the songs are in. Go to tools>options>sharing> shared folders and add the folder(s) This can also be done via the Limewire Library, but I prefer the first way. If you choose to remove them on no account use the delete feature. in the Limewire library You will loose the files totally (unless you are running 4.13 Beta Limewire)
Just be careful to only share what you want to and no personal documents etc!!!!. Some share over 4000 and that is really rather too many, in my humble opinon
If you share "several thousand" it is likely to slow your system excessively .
Thanks for the files .. and I hope this helps
