share the root folders/directories of all your music directories (DONT share your entire C: drive!). limewire will recursively share any subdirectories that you wish to share. if there are any files that you wish to not share and are being shared, you can unshare them by finding them in the library and right-clicking the file, then press stop sharing. you can also unshare any folders/directories you wish.

just take some time to learn your own system. make sure you have basic computing knowledge before using the internet, then learn the basic knowledge that it requires!!
