Switch to 7-zip compression.

I decompressed wxAll-2.5.3.zip and recompressed it using 7zip. The results were: wxAll-2.5.3.zip: 19.014.838 bytes wxWidgets-2.5.3.7z: 8.355.485 bytes That's 43% of the original filesize. It takes a bit more to compress, but with that ratio, it's more than worth it.

Is this fully compatible with (pk?)zip? Does it decompress with software such as WinZip, XP built-in support, WinRAR?

No it's not, it's a whole new method of compression (open source, it's on sourceforge as a matter of fact), but it's catching on rather quickly as many projects use it, and you can create a self extracting .exe with a few KB overhead that extracts the files by itself without the use of any external programs.

zip format is arguably the most accessible archive format (especially on Windows). Aren't tar.gz files also available, how do they compare to 7zip?

As you can see on the download page, tar.gz is 17.706.090 bytes, and as I mentioned 7zip is less than half that. And it is true that .zip is the most accessible format, but a self- extracting .exe would be even more accessible, since the user would not need another program to extract it with. It wouldn't run on other OSes though. Maybe you could add a 7z release alongside it and see how downloads go?

The decision here is not mine to make. I personally don't believe it would be useful due to 7zip still being a niche-ish market, but without anyone using it it would never catch on, of course. :)

Hi!

Being also part of the other community I noticed somebody who made comparison which fits into this feature request. Take a look at http://www.cs.tut.fi/~warp/ArchiverComparison/ . I do not use 7zip myself but I think such benchmark is an argument for consideration. Regards,

I think now that release creation is automated, we could easily create 7zip-compressed archives too. But this is hardly urgent.

BTW, I can indeed reproduce big savings in the file sizes. For example, for wxMAC-2.7.0-1 we have:

.ZIP 15156 KB .tar.gz 12475 KB .tar.bz2 9117 KB .7z 7470 KB

FWIW for 2.91 the numbers are proportionally the same:

zip: 26MB tar.bz2: 16MB 7z: 13MB

I will experimentally make 7z version available for download as being twice smaller is an important advantage IMHO. Then we'll see how many people download it compared to the zip version and will decide whether to provide it for 3.0.

This bug is six years old, when I opened it I had a 33.6 Kbps connection, so downloading a 7zipped file took an hour less. Now it takes ten seconds less, so it doesn't much matter, but thanks for addressing the issue.

Didn't we supply 7z archive with latest 2.9.x release?

Oh wow, this is still open? It's been seven years, I can download this on my mobile connection and size will barely make a few seconds' difference. Please clsoe this seven year old enhancement request as irrelevant, as it's rather late to be discussing it.
