seriously bzip2 would be the best compression, but you Windows user might not be familiar with it.

7zip cannot compressed into rar files and WinRAR cannot compressed into 7z files; is it because they cannot make it or because of the copyright issue for the compression algorithm?? and the winzip format is copyright free/open source?

Seriously, that's a non-issue to me as usually .zip is the widely use format (as far as my work is concerned)

While WinRAR is more popular and perhaps powerful, I choose 7zip because it is free and quite easy to use

Powerful as in what part? The only thing that I can think WinRAR being a powerful tool is that the software itself has better user-friendly functions (short cuts, tips & helps, etc) compared to 7zip. Though, the functions are simply similar to which both WinZip and 7zip have. Based on compression, 7zip is better than WinRAR.

I pick 7zip, free :-) and 7z format is used by some exe installer maker e.g. NSIS because of it higher compression rate.

And some open source application have an option to download 7z format file.

I previously use winzip/winrar.

But just switch to 7 zip recently.

7zip ain't bad considering that I just zip and unzip. Hardly touch any other functions. Moreover, it's free. Why not?

i believe winrar is multi-threaded, hence it will take advantage of multi-core processors and is faster than 7z when compressing and uncompressing

I pick 7zip because there's an x64 version.
Plus it's free.

If you'd like high compression ratio, I'd recommend KGB Archiver but it takes 3 days to archive/compress 2GB into 2MB (Yes, it's possible!).

Ever tried uncompressing the file back to its original? How long does it take? Is the unpacked file 100% the same with the original?

You could hash the source files and the unpacked file with MD5 for this purpose.

I for one believe lossless compression does have its limits. It depends on the data. And 2GB into 2MB for typical, usable files (videos, audio, documents) is downright impossible.

Prove me wrong. Because I'd rather spend uncompressing a 2GB file in 3 days, offline rather than downloading a 2GB file for 2 days.

You don't need to spend 2 days to download a 2GB file... nowadays we have broadband...

You need only approx. 3 hours to download a 1GB file if your broadband connection is 1Mbps.

I don't think that holds true for BitTorrent transfers, as it is being throttled by our thoughtful and friendly ISPs despite the availability of bandwidth.

7zip... more user friendly(my opinion), more features (pause, estimated time, run foreground, comp/expand speed), Free (no need get piratx version) and zip format is more than enough for send files over internet

7zip FTW!

sure or not? blink.gif I would like to try ...

Anyway, I use 7zip most of the time. It is faster to compress/extract/open the file. thumbup.gif

Its depend on the source,

eg for jpeg image and mp3, they are already compressed by lossy enocder, its unlikely can be compress any futher.
