File packers?

Hi.
I've noticed recently quite a lot of people use file packers to protect the media in their games.
Can someone direct me to/recommend some good, easy-to-use file packing systems?

I think "filax" favours that one.

I wonder why???

I haven't tried filax's packer yet but it looks pretty good. Thus far I've been using Terabit's packer Datapak, and it has been working well.
