Best Compression Program?

Best compression program? WinRAR seems to not want to unzip these files.

WINACE

Winzip 8.1 SR-1

try reinstalling Winrar.

Try ZipGenius is freeware or IzArc.

Thanks y' guys. I'll try Winzip.

EDIT:
Yep, Winzip does appear to be doing it. They're 100+MB zip files...

Ever looked into UHARC? For compressing I mean.

For ZIPs, I'd recommend WinRAR or ZipMagic.

I've tried both and they're both reliable :)
