7-Zip - meeting all of your file compression needs (and then some)
by Jason Clarke Jul 29th 2007 at 7:30PM
It's 2007. Why the heck is file compression still a pain in the ass? Most people have standardized on the Zip file compression format for compressing files, however there are a few out there that feel the need to point out that RAR offers superior compression ratios. Dealing with those two wasn't really that bad, but now we're starting to see newer algorithms that are providing noticeably improved compression ratios. What to do?
Get yourself a copy of 7-Zip. 7-Zip can unpack RAR, CAB, ISO, ARJ, LZH, CHM, Z, CPIO, RPM, DEB and NSIS files, and can create 7z, ZIP, GZIP, BZIP2 and TAR files (and obviously unpack those as well).
The 7z file format is 7-Zip's claim to fame, with approximately 40% better file compression than a "compatible" zip file, and around 10% better than RAR, the previous file compression champion. 7-Zip's official release is for Windows, but the site links to unofficial Linux and Mac versions.
Now you can start sending your friends and business associates files that they have no idea what to do with! Either that, or you can standardize on the 7z format, and know that your files are smaller than everyone else's. Or you could just use it to create and unpack Zip files and stop trying to be so damn superior.

With Halloween fast approaching, it's a great time to get in some practice defending your territory against zombies. In Graveyard Shift, you take aim at zombies and other creepy-crawlies, blasting them into splatters of cartoony green guts. It's a casual first-person shooter, and it's very easy to get the hang of - use the mouse to aim, click to fire. Graveyard Shift has at least 15 levels, and it might even have some secret stages I haven't unlocked yet.
They key to getting good at Graveyard Shift is learning to use ...

7-Zip is great and easy to use. Some people have had problems with the current release under Vista, but it works fine for me. (Vista Business and Ultimate)

Someone invents a better mousetrap, and the mice get smarter. So someone invents an even better mousetrap. It's called progress.

Even I don't like it everytime a new format comes along claiming to be superior than good ol' Zip and RAR, but the new 7z comression format is the last reason to use the 7-Zip archiver.
I switched to it a couple of years ago because its fast, it's small, it's open source and it supports extracting from Zip as well as RAR files. There's nothing else out there that's so good and yet is open source. I even prefer it's minimalistic appearance to the very 2000-style, unnecessarily ornate default skins of both WinZip and WinRAR.
So don't think of 7-Zip has a 7z format archiver; think of it as a replacement for your WinZip or WinRAR.
For me, it's 7-Zip for life.

Dunno about that, I've found that 7Zip does some things poorly when compared to WinRAR, my old stalwart. Example: select several archived files, then right-mouse drag them somewhere. IIRC, with WinRAR, you get an "extract all files here" and an "extract to individual subfolders", and either command spawns a single WinRAR process. With 7Zip, I think it only gives you the "extract here" option, and spawns one process per archive. Unless and until somebody gives me a better reason, I'll be using WinRAR for all the file formats it can handle.
