I compressed a folder containing 177Gigs. After compression the .zip file is 177Gigs. I thought compressing made the folder smaller. That's what compression means right.

What am I missing?

It depends on what you're trying to compress. Some files lend themselves to compression and some don't.

Thanks. I compressing photos and videos. Not much point. I'll have to buy some hard drives.

That's right. Photos and video generally don't lend themselves to much compression, unless you transcode them and sacrifice quality. Fortunately, hard drives aren't very expensive.

Photos and videos are already lossy compressed, so they don't take well (or at all) to lossless compression.

Yes, HDs are cheap, now that prices seem to be returning slowly to pre-Thailand-flood points. I also have this huge 150G vid folder, I've decided to off-load it to 2 externals, so that I can update my boot HD to a SSD.
