  1. Good compression ratio
  2. Opens almost anything
  3. Free. What more could you ask for?

Opening an image in archive leads to this:
"Windows Photo Viewer can't open this picture because either the picture is deleted, or it's in a location that isn't available."


Last time i tried with WinRAR i ended up with a similar message. If you really want to open the jpg then assign an alternative image viewer like XNView for example. It works.

I bet that it's not only a 7-zip problem since XNView works.


try haozip


+1 to bugs in 7zip at Windows 8. Problems with temp folders, file associations... I'm changing to another software.

Some random stuff...

The most popular formats are zip, rar and 7z.

Zip is free, but its features are quite limited nowadays.

Rar has quite a lot nice features.

7z does not have recovery record feature, but that is not very important, for my experience these years, I'm not helped with WinRAR recovery record feature. Internet transfer corruption? I did not experienced that.

The compression ratio is not that important like earlier days. So Rar cannot be called "bad" in most cases. The most superior of 7z is lossless bitmat compression (like BMP).

Do we need other formats?
There are arc format from Small FreeArc iconFreeArc, b1 format from Small B1 Free Archiver iconB1 Free Archiver, kz from Small KuaiZip iconKuaiZip, PEA from Small PeaZip iconPeaZip, if there are more good format, please comment. Arc is better IMO, and it is still in developing. But all of these do not have big difference, and the newer ones do not supported by most archivers. Self-extract archive with exe? Not a bad idea but is it really necessary for us to do that? It will confuses people IMO. So maybe we still just needs 7z.


I mostly use 7z unless I've to send data to low-tech guys that does not know other format than Zip.
Rar is also an excellent format due to recovery records, something Arc seems to be trying to do in open source flavor - a nice plus, but I've never had to rely on it, nothing is better than doing proper backup!
There is also Zipx from WinZip, that quite catch up lower range of 7z and Rar compression, but in my experience it is too slow for what it offers.


The 64-bit version is not working very flawlessly with Wintdows 7 64-bit. Other than that,4/5.


Themes for 7-Zip

Comment by DanMan about 7-Zip Apr 2011

To remedy the ugly looks of both the program and the icons, try 7-Zip Theme Manager

the best file archive utility ever

Positive Comment by trekeyus about 7-Zip Also mentioning: WinZip Mar 2011

The best file archive utility ever. I just wish they would implement zipx faster so i can remove Winzip.


Everything what we need in a little application. Without an spezial theme of some shit.

Only that, what we need. Freedom :D


Much better than WinRAR or any other file archive utility

Positive Comment by ThomasKri about 7-Zip Also mentioning: WinRAR Jan 2011

Much better than WinRAR or any other file archive utility, hands down.


Great extractor and nice replacement for explorer

Positive Comment by Xeogin about 7-Zip Also mentioning: Windows Explorer Jan 2010

Great free extractor, and works nicely as a replacement for explorer on a Hyper-V server! xD


7zip works great for me on Ubuntu and I always used it on Windows.
It compresses better than any other program I have used so far.
