Do I have to keep files in both the shared and saved folder??

Hi, I am sure that this is probably addressed somewhere in the forums, but I have been reading the better part of the night and day and still can't figure out the answer to my question.
I just purchased and downloaded limewire pro yesterday. Already I have downloaded quite a few songs (thank you all so much for having them) and am having a problem with my computer totally freezing up solid several times an hour.
I have done all of the things that I have noted here in the forums to preven this, but it is still freezing.
Anyway, my question is this: do I have to keep both librarys (with identical files) in my computer in order to share them, or may I delete one or the other and the other members still be able to upload from me? I want to share all of the wonderful music I am downloading, but don't see the sence in having two identical librarys full.
Thank you in advance for any help, assistance, and information provided.
