Too bloody right!

I've been using WinRAR since the day it came out (commandline FTW) and I've always sneered at the inferior WinZIP/WinACE tools of old ... I also tended to ignore 7zip for the most part. Sure I'd heard about how awesome its compression ratios are and how it properly utilises threads .. but I never really used it. Until now. Whoa.

Extracting an 8GB archive and WinRAR said it was going to take 11mins. That's ungodly slow, especially on a proc like mine -- so I tried 7zip instead. BOOYAH! 5m2s to extract Very Happy

*does the happy dance*

I'm interested in compression. Is it better than winrar or same?

I've not tried it yet, though I've heard it's meant to be CONSIDERABLY better (upto and including 40% in some cases)

I'll give it a try with a few things.

The only reason why I still keep both (as opposed to only 7Zip) is the butt-ugly interface of 7Zip... Sad The moment a new interface is put, I will move to 7Zip completely.

SAME!!

Jesus, I was *just* talking to my girl about that .. and I said the very same thing you did! "The only reason I don't use 7zip primarily is because the goddamn ugly interface"

Very Happy Very Happy Very Happy

Anyway, just some quick results. Compressing random shit found in my GAMES folder.. heh. I'll compress some ISOs later, but I'm busy at the moment so I didn't wanna tie up my comp with lengthy compression tasks.

7zip *is* better than WinRAR .. but it's not exactly "Ooooh, WinRAR suxx0rs the ballz" 7zip does win on speed though. It's a lot faster at compressing AND decompressing.

Quote:

AudioSurf. Original folder size: 105MB. 7zip compressed: 64.3MB. WinRAR compressed: 78.4MB.

Space Hack. Original folder size: 387MB. 7zip compressed: 219MB. WinRAR compressed: 240MB.

Neuro Hunter. Original folder size. 1.31GB. 7zip compressed: 747MB. WinRAR compressed: 834MB.


Obviously if you're compressing pre-compressed archives (like .PAK, .ZIP, .CAB or even MP3s) then you won't get much difference between the two. UHA is what you need for stuff like that.

worked for me

EDIT: right, 7zip cant archive rar and winrar .7z...
edit2: both extract .rar at same speed for me, 10s here and there

and about gui: it's not like you're gonna jerk off on the interface.. i'd like my things to look as minimalist-dirty as possible


yes

7zip looks great, and I would have changed to it by now if it wasn't for the fact that it doesn't support creating rar archives.

When I create a rar archive it's pretty much guaranteed that the other party can extract it. 7zip archives, not so at all.

Yeah, I was surprised that 7zip didn't support RAR. Luckily though, latest versions of WinRAR *can* extract from 7zip.

they can extract, but they can't ARCHIVE both each others' format.

RAR is proprietary
7z is under lesser general public license - meaning it's free but only author can modify its source

Quote:
Unlike WinRAR, 7z cannot extract "broken files" - that is (for example) if one has the first segment of a series of 7z files, 7z cannot give you the start of the files within the archive - it must wait until ALL segments are downloaded. WinZip has the same limitation.


yes

should be mentioned that compression ratios are very dependant on materials.. winrar is still a bit better on much of binary data
especially annoying when 7zip takes decades longer compressing and ends up with a larger file anyway

You should try the free multi-archiver Peazip :

P.S.: And WinRar still has a really nice compression-to-speed ratio.
