Best Upzip software

[energyguy]

I got a new PC recently and just noticed when i came to try and unzip a rar file, there is no pre-loaded software.

For those of you that use them regularly what is the best freeware unzip software available?

I use 7zip. http://www.7-zip.org/

REALLY lightweight and simple. You don't even have to open a program to extract the file, you just right click it and tell it to extract somewhere.

Seconded. We use 7Zip at my office and I have it at home. It's a very good product.

I used to use IZarc, but their latest release has been installing adware and they've been downright insulting to anyone not wanting it, so I switched to PeaZip.

I've used WinRAR for a while, but I don't know much about the recent versions of it.

I've always used WinRar, even if it's a trial version, it still lets you unzip/compress files.

I still use Winrar out of habit sometimes on new pc's and my custom built windows install comes with it already.... 7zip, though a little irritating with some of it's gui aspects, is the best free one i've seen.
