I come from a DOS background, where in the late '80s we started out with .arc and .pak, which migrated into .zip
JAR was available in 1996 or so, I think. I still have copies of most of the archivers and compressors I was playing with in those days... anyone remember UC2? HA? SAR? ACB?
Not really.
pkzip2.04e, yes, I still remember the version number, so it must have been the standard for some time :-)
