If you're going to use a traditional p2p app then I would suggest dumping limewire and trying out "soulseek". It should be the first result if you google that.

I haven't used ss recently so I don't know how the current versions are or what the community is like but a couple years ago it was by far my favorite p2p application.

Otherwise I'd suggest using news groups, ftp, or torrents. Faster, easier, and safer.
