WinRar or WinZip?

Dear Experts:

Hi!

I just tried both WinZip and WinRar to compress a 39.3MB folder.
The file size of the compressed was:
WinZip:   36MB      (WinZip 12.0 evaluation copy)
WinRar:   26.2MB   (WinRar 3.80 evaluation copy)

As the above numbers may indicate, the compression ratio is very disappointing.
Is it so because I used evaluation copies?
Overall which one is better?

My second related question is:
When I sent a folder compressed by WinRar to someone who has Winzip,  should the
receiver have WinRar too to open the folder?  


Thanks a lot!

Winrar archives have better ratio indeed. You can choose when you archive with winrar to archive as .rar or.zip. The send to archive option can be modified from settings. Both have command line tools, but if you use zip you can extract or archive even without winzip in windows xp/vista machines, if some dlls are registered.

By me I will support Winrar.

Thanks a lot for your kind, prompt tips.

By the way, is an evaluation copy different from a licensed copy in terms of compression ratio?

I compressed a folder, using an evaluation copy of both WinRar and WinZip.
The folder was compressed as the follows:
The file size of the compressed was:
WinZip:   36MB      (WinZip 12.0 evaluation copy)
WinRar:   26.2MB   (WinRar 3.80 evaluation copy)

Thanks!

Winrar can also extract ISOs which can be very handy

--nope, although in winrar you can set it to a higher compression ratio and compress it more.
