With Frostwire, the shared folders start out empty and can be filled manually by you. You also automatically start sharing any file that you download with Frostwire.
Files over 20MB are better shared with BitTorrent because you don't need to be online for someone to download a file shared with BitTorrent (except for the first day or two).
It is illegal to share files that are copyrighted. You are likely to be caught on Frostwire/Limewire/Shareaza. BitTorrent is safer. [ theymos's advice column | Ask theymos A Question ]
