P2P file Sharing Programs

Hi,
I heard that programs like eMule are free and you can download huge file from all over the net!
I want to know is it safe to use these sort of softwares?
and ho they work? And is it legal?
I downloaded the software and i searched for "ISA server" and it returned alot of results seems to be very useful!!
I googled it but i couldn't find good answers, so
I'll be thankful for help.

Yes, programs like eMule are free and you can download programs such as ISA Server, but it is illegal to download software for which you didn't pay.

You have it there in a nutshell. Peet-to-peer filesharing programs and torrent downloads are fine - it's just a technology after all - and you can get many useful downloads on there, but be careful that you only download legal stuff. The authorities do monitor such channels looking for software, music and video piracy since that's where they are most likely to find it

Also be careful with these types of download as they can be riddled with viruses....so it comes with risks aswell as the other things highlighted.

My policy is to only use torrents which have been advertised on legitimate sites. It's just not worth the risk for me.

well, i think i'm not going to use it since it requires some specific
network configuration and a dedicated internet line to get better
results, thanks for your replies it really helped me.

regards,
