Helping people with computers... one answer at a time.
Read the article that everyone's commenting on.
As my rusty memory recalls, Phil Katz (the "PK" in PKZip) originally crafted a clone of the SEA ARC compression utility called PKARC. SEA sued Phil, so he created his own compression standard - ZIP - in 1989. At the time the computer bulletin board systems were awash with different compression types - ZIP was fast, efficient, and free. BBS operators began to use it in droves. I'll have to give 7-Zip a try!

ARC is still around. Howard Chu released it on a GPL in 2003. It can be found in a lonely area of sourceforge.net.
I was always amazed about how quick pkzip replaced SEA ARC as the standard.
Interesting story. I'll try 7zip.
Other nice things about 7-zip: The GUI is very simple and easy. No wizards, everything is in a single window. It can create self-extracting archives. Better yet, it can create encrypted, compressed, password protected, self-extracting archives.
I'm tring 7-zip in command line mode, do you know if it is possible to make 7-zip file with password?
I have try the option -p butte this will ask me a psw, and after compression if i try to use winrar to open 7zip file, i can and don't ask me for any password.
I need to use commandline argument to extract a password protected zip file during unattended scheduled operation.
I see how to create an archive with password from commandline. But I have not found how to extract from commandline a password protected file except for attended use, when a human is there to provide a password in response to a prompt. Can anyone help?
I found it ... same as setting, just use -pPassword
7za e archive.zip -pPasswordHere
Dave: Your memory isn't that rusty. SEA sued Phil Katz for infringing on the ARC format. Katz then created the ZIP format and placed it in the public domain. The BB community was so incensed at SEA that they boycotted them and moved to PKZIP or another one of the ZIP tools.
Thanks, Leo! I was just about to plunk down $15 to upgrade my WinZip. Now I'll download 7-Zip instead (and buy Leo a Latte to celebrate :-) ).
