As I do as well. That was a bit tongue in cheek. Still, pkzip was widely distributed before the Internet got really going via BBSes. Nearly everyone with a modem had a copy. It wasn't until Windows 95 (at least) before compression/archiving became something that was "standard" with the OS (at least in DOS). > Encryption was not the only problem.

But we've had them too for as long as I can remember -- they're callsed shell archives. Still you need some way to encrypt the file. On the other hand, if the OP wants to be able to extract (cleartext) files, why should the archive be encrypted in the first place? In case people aren't familiar with them, shell archives are really kind of neat in that they contain a shell script that extracts the files inside the shell script,via what's called 'here' documents (in shell, this is a 'file' that's embedded in a script.) #! /bin/sh # sample here document extractor cat >extracted-file <<!EOF * this is a test of the emergency broadcast system this is only a test !EOF More recently, we see self-extracting archives where all the (binary) data is embedded in the script -- for example, open office's installer. > > Saludos > -- > __ > / \\ @ __ __ @ Adolfo Bello <[EMAIL PROTECTED]> > / // // /\ / \\ // \ // Bello Ingenieria S.A, ICQ: 65910258 > / \\ // / \\ / // // / // celular: +58 416 609-6213 > /___// // / <_/ \__\\ //__/ // fax : +58 212 952-6797 > www.bisapi.com // pager : [EMAIL PROTECTED] > > > > ------------=_1048329598-1281-1763 > Content-Type: text/plain; name="message.footer" > Content-Disposition: inline; filename="message.footer" > Content-Transfer-Encoding: 8bit > > Want to buy your Pack or Services from MandrakeSoft? > Go to http://www.mandrakestore.com > > ------------=_1048329598-1281-1763-- >
