[2005] Compression

Hello.
I'm making a backup utility, and I need to know how to compress files. Is there a VB built-in utility for this? Also, if possible, can you tell me how to compress things to the maximum?

Thanks!

I think the SharpZipLib is probably your best bet. It is really easy to use and creates standard zip files.

Try DotNetZip Library as well. I'm using it ATM in a project of mine and I'm really satisfied.
