Public Folder

Public Folder was an early file sharing utility for Macintosh System 6 created by Michael Peirce at Claris.

Description
Public Folder was accessed through the Chooser and brought up a simple dialog box in which the user selected what file to fetch from another Mac on an AppleTalk network that also had the Public Folder extension installed. Version 1.0, dated September 20, 1989, was distributed to users for free. It was updated to version 1.01 in 1991.

Compatibility and discontinuation
Claris issued an advisory that installing Public Folder with Vaccine 1.01 and Mirror by Central Point Software on the same Mac would cause it to crash upon startup. The utility fell out of use after System 7 introduced file sharing as a standard feature in 1991.
